Woodstock High School, Woodstock • SCIENCE 1035B, Truckee Meadows Community College • BIOLOGY 190, Isaac Perez Quintero - Transformation lab.pdf, University of California, Davis • BIOLOGY 2A. If there is no ampicillin in the agar, E. coli will cover the plate with so many cells it is called a "lawn" of cells. STUDY. This is a lab report assignment to accompany the pGLO Bacterial Transformation Lab done in many AP Bio and Biotechnology classes. Spell. A bacterial colony is a large group or cluster of bacterial cells that originated from a single, clonal cell. What would you expect your experimental results to indicate about the effect of ampicillin on the E. coli cells? Moreover, the colonies on the LB/amp/ara plate should fluoresce green. If a white colony was streaked onto an LB/amp/ara plate, the resulting colonies would be green. What does this observation indicate about the source of the fluorescence? What traits or characteristics should the organism have (or not have) to be sure it will not harm you or the environment? Title: pGLO Transformation Lab Introduction: Genetic transformation is a change caused by genes, involving the insertion of a gene into. Bacterial Transformation Lab Review. What is the total volume of reagent in mL? Which of the traits that you originally observed for E. coli did not seem to become altered? Comments. Think about these questions before collecting data and analyzing your results. As this biology bacterial transformation lab answer key, it ends taking place brute one of the favored books biology bacterial transformation lab answer key collections that we have. Safety is another important consideration in choosing an experimental organism. If a green colony under UV light was streaked onto an LB/amp plate, the resulting colonies would be white with no fluorescence. Relate the use of bacterial transformation in biotechnology. What is the function of the “-DNA” tube. The multiplication of a single bacterium on agar plates appears as a colony. Gravity. In the space below, list these non-transformed traits and how you arrived at this analysis for each trait listed. Roanne. From your results, can you tell if these bacteria are ampicillin resistant by looking at them on the LB plate? Bacteria which resemble the non-transformed will be found on the LB/(-) pGLO plate. If ampicillin negatively affects the growth of E. coli, then there should be fewer colonies of bacteria on that plate. The scenarios were as follows, one plate with plasmid, one without and one plate with ampicillin and plasmid and one with ampicilin and without plasmid. when a host organism takes in foreign DNA and expresses the foreign gene. Course Hero is not sponsored or endorsed by any college or university. mocha_dog529. Thus, the plasmid must confer resistance to ampicillin. Get a verified writer to help you with Experiment on Bacteria Transformation. A bacterium would be the best host organism. pGlo plasmids, when taken up by a bacteria, will code for. State the purpose of each component of the experiment Components: 1. Equal amounts of cells could be plated on two different LB nutrient agar plates, one which contains just LB nutrient agar and one which contains LB nutrient agar ampicillin. If the bacteria are viable on the LB/amp plate, then they are resistant to ampicillin. The plasmid must express a gene for ampicillin resistance (the protein product of the bla gene codes for beta-lactamase, the protein that breaks down ampicillin). By introducing a new gene into an organism via a vector (DNA molecule used as a vehicle to artificially carry foreign genetic material into another cell) (plasmid, virus, etc.) Explain your answer. Thus, they are virtually identical to the non-transformed starter colonies. Match. AP Biology, MODS 19-21.

This plate contains arabinose which induces expression of the GFP gene and generates green fluorescent colonies. Student involvement in this process will result in an increased understanding of the scientific process and the value of proceeding into a task in an organized and logical fashion. RE: bacterial transformation lab help? To dispose of contaminated material: Immerse all disposable pipets, tubes, and loops that have come in contact with bacteria in 10% bleach solution for at least 20 minutes before draining, rinsing and disposing of in the trash. Addresses AP® Biology Big Ideas 1 and 3 and Essential Knowledge 1.A.1, 1.A.2, 3.A.1, 3.C.1, and 3.C.2. A successful experiment will be represented by the presence of colonies on the (+) pGLO LB/amp and (+) pGLO LB/amp/ara plates and the absence of colonies on the (-) pGLO LB/amp plate. Bacteria are small, single-celled organisms which reproduce quickly and easily. Describe the evidence that indicates whether your attempt at performing a genetic transformation was successful or not successful. The expansion puts pressure on the weakened cell wall, which then ruptures from the pressure. This process creates a uniform electrical field that allows motion of particles of various sizes towards a positively charged end. study of biological processes, observation of cell movement, use of GFP as a visual marker. Explain your answer. a green fluorescence protein GFP. What happens to an unopened soft drink when it freezes? Helpful? Learn. The LB/amp (-) pGLO and the LB/amp (+) pGLO plates should be directly compared. Explain your prediction. Be sure to. Why? Please sign in or register to post comments. Thus, there should be few, if any, bacterial colonies present on the ampicillin plate. The bacteria on the (+) pGLO LB/amp/ara plate should appear whitish when exposed to normal, room lighting, but fluoresce bright green upon exposure to the long-wave UV light. If the sugar arabinose is present in the growth medium it is beneficial for bacteria to produce the enzymes necessary to catabolize the sugar source. Abstract. Transformation Lab A Plasmid Discovery Labratory 6, AP Biology Abstract. Although the E. coli strain used in these experiments has been rendered non-pathogenic, it is important to teach the students good sterile technique and safe disposal of bacteria. The sugar arabinose turns on expression of the GFP gene by binding to a regulatory protein, araC, which sits on the PBAD promoter. The bacteria we might generally call "bad" for us include those responsible for causing illnesses like food poisoning. This Site Might Help You. Bacterial Transformation Lab Answers bacterial plasmid-based genetic transformation, enables students to manipulate genetic information in a laboratory setting to understand more fully how DNA operates. Spell. The transformation of bacterial cells is a useful experiment to help develop an understanding of transformation by plasmid DNA. No. How would you change the bacteria's environment to best tell if they are ampicillin resistant? The transformation effectiveness was then determined by analyzing the amount of resulted colonies created. Before undergoing the transformation lab, confirmation that the substance being added to the bacterium is DNA must be acquired. Without this control, one would not know if the colonies on the LB/amp (+) pGLO plate were really transformants. In the Transformation Lab designed by the Carolina Biological Supply Co., we took extracted DNA and inserted them into E. Coli bacterial cells through the transformation process (Carolina Biological Supply Co. 2014). Hello, I need a little bit of an assistance with a biology lab about bacterial resistance to antibiotics involving the incorporation of antibiotic resistant plasmids. 1285 Bacterial Transformation Virtual Lab - A.P. Gravity. Explain the process of bacterial transformation. This exogenous DNA can be recombinant DNA molecules that have been constructed in vitro, as well as natural DNA molecules. 2.

If ampicillin has no effect, there should be approximately equal numbers of colonies on both plates. record your answers in your laboratory notebook. Learn. Bacteria are a whitish color. E. coli colonies you initially observed? 1 Ms. Strachan/AP Biology Bacterial Transformation (Virtual Lab) Table 1. I just need help with formulating the hypotheses. Genetically transformed cells have taken up the pGLO plasmid which expresses the ampicillin resistance gene—these cells can survive on the plates which contain ampicillin. Based on the above considerations, which would be the best choice for a genetic transformation: a bacterium, earthworm, fish, or mouse? The organism should not produce any toxins or compounds which could make people sick. Source(s): https://shrinke.im/a8qbl. What are 3 real-world links for the study/use of genetic GFP? An unsuccessful experiment will show an absence of colonies on the (+) pGLO LB/amp and (+) pGLO LB/amp/ara plates. What was the purpose of each plate?" and this "How did you identify transformant cells?" I'm stuck on these two question. Created by. These bacteria were removed from the starter plate, did not have any plasmid added to them, and were replated on an LB plate. When exposed to UV light, the electrons in GFP's chromosphere are excited to a higher energy state. Answers are provided in the Teachers Answer Guide. In this investigation, students will first acquire the tools to transform E. coli bacteria to express new genetic information Page 3/5. What two factors must be present in the bacteria's environment for you to see the green color? Transformation is the process by which a bacterium takes up and expresses exogenous DNA, resulting in a newly acquired genetic trait that is stable and heritable. When they drop down to a lower energy state they emit a longer wavelength of visible fluorescent green light at 509 nm. An organism which reproduces quickly. Scientists often want to know if the genetically transformed organism can pass its new traits on to its offspring and future generations. In this experiment, both (-) pGLO plates are control plates. The best way is to compare the control to the experimental plates. bacterial transformation lab answers quizlet pglo bacterial transformation lab answers virtual lab answer key Some results have been removed. Classzone Bacterial Transfomation Virtual Lab Answer Key There can be 10 to 200 copies of the same plasmid within a cell. 1.

This lab also explored the effect that certain environments would have on the bacteria, including those containing antibiotics or certain sugar molecules, as well as how the introduced gene would interact with these environments. We transformed E.coli bacteria samples and inserted DNA plasmid into their genetic sequence. Conversely, what would happen if you took a white colony from the LB/amp plate and streaked it onto an LB/amp/ara plate? Learning Goals: Transform bacteria using the pGLO lab procedures Big Ideas: To develop newly acquired skills in the laboratory. Conversely, if arabinose is not present in the nutrient media, it would be very energetically wasteful to produce the enzymes to break down arabinose. The bacteria need to be ruptured in order to release the GFP/plasmid DNA, which can then be purified using column chromatography. Write. The transformed cells are found on the LB/amp and LB/amp/ara plates. 1. This comparison shows that genetic transformation produces bacterial colonies that can grow on ampicillin (due to the uptake of the pGLO plasmid and the expression of the ampicillin resistance gene). Created by. Transformation is the introd… Attleboro, MA 02703 (508) 222-5150 ext. "After transformation, four different plates were streaked with bacteria. fatpanda80. To get this information, which would be a better candidate for your investigation, an organism in which each new generation develops and reproduces quickly, or one which does this more slowly? Flashcards. Do you observe some E. coli growing on the LB plates which do not contain ampicillin/arabinose? Match. Gene regulation allows for adaptation to different conditions and prevents wasteful overproduction of unneeded proteins. © Copyright, Cold Spring Harbor Laboratory.All rights reserved. If the genetically transformed cells have acquired the ability to live in the presence of the antibiotic ampicillin, then what can be inferred about the other genes on the plasmid that were involved in your transformation procedure? Cells that were not treated with the plasmid (LB/amp (-) pGLO and LB/amp/ara (-) pGLO plates) could not grow on ampicillin, whereas cells that were treated with the plasmid (LB/amp (+) pGLO and LB/amp/ara (+) pGLO plate) can grow on the LB/amp plate. 24 2. The ara control region regulates GFP expression by the addition of arabinose, so the GFP gene can be turned on and off by including or omitting arabinose from the culture medium. DATA/RESULTS o NOTE o You have to enter your data into the “LAB NOTEBOOK” in the virtual lab (top right-hand corner of the screen) AND also rewrite it into the data table below for credit on your worksheets. This could be a result of not adding a loopful of plasmid to the (+) pGLO tube or not adding a colony of bacteria to the (+) pGLO tube. Antibiotics usually kill bacteria (are bacteriocidic) or inhibit their growth (bacteriostatic). Bacterial Transformation Lab Report: Transforming E.coli strains with Green Fluorescent Protein. Can you explain why the bacterial cells' outer cell wall ruptures when the cells are frozen? pGlo plasmids, when taken up by a bacteria, will code for. This is done through electrophoresis. What advantage would there be for an organism to be able to turn on or off particular genes in response to certain conditions? 0 0. PLAY. Bacterial Transformation Lab Answers. In the lab, we incorporated the plasmids into the bacteria and put them into a medium with an antibiotic. Students discover and explore the process of Look at the colonies of E. coli on your starter plates. Good examples of highly regulatable genes are the enzymes which break down carbohydrate food sources. 0.250mL or 250 microliters. Why? The presence of any colonies on the ampicillin plate would suggest that those bacteria are resistant to the antibiotic ampicillin. Bacterial Transformation Lab Report. You cannot tell if the bacteria are ampicillin resistant just by looking at them. Yes. Each colony can be seen by the naked eye, while a single bacterium requires a micro-scope for observation. The bacteria on the (+) pGLO LB/amp plate and the (-) pGLO LB plates should be whitish. STUDY. The pGLO plasmid DNA and the original bacteria can be eliminated from providing the fluorescent source. Subjects: Science, Biology, General Science. The purpose of this lab was to study transformation and the effect that integrating certain genes into a typical E. Coli bacteria would have on the cell. The best test would be to take some of the bacteria growing on the LB plate and streak them on an LB/amp plate. Related documents. A control plate is a guide that is used to help you interpret the experimental results. Recall what you observed when you shined the UV light source onto a sample of original pGLO plasmid DNA and describe your observations. List those traits below and describe the changes that you observed. University. Since only some of the cells exposed to the amp R plasmids will actually take them in, only some cells will be transformed. When a bacterial cell freezes, the volume of cytoplasm expands. Recall that the goal of genetic transformation is to change an organism's traits (phenotype). To get acquainted with bacterial transformation applications in society.

Which of the two possible sources of the fluorescence can now be eliminated? Genetic transformation occurs when a cell takes up and expresses a new piece or foreign ____________, often a circular plasmid. Which plates should be compared to determine if any genetic transformation has occurred? Thus you will see only individual colonies on the plate. 5 years ago. Can you predict what would happen if you took one of the green colonies from the LB/amp/ara plate and streaked it onto an LB/amp plate? In this experiment, bacteria will be transformed with a gene that codes for Green Fluorescent Protein (GFP). Both types of bacteria (those that are ampicillin resistant and those that are ampicillin sensitive) look similar when cultured—think about the colonies on the LB starter plate and the colonies on the +pGLO LB/amp plate. Instead of having students answer the "cookbook" pre-lab and post-lab questions where they can find the answers online, I have them write a formal lab report.The resourc. In the transformation lab, we discovered the process of bacterial genetic transformation and how to calculate transformation efficiency. Terms in this set (12) What is bacterial transformation? (Possible answers: E.coli within the intestines of mammals, bacteria within the soil, bacteria used to make foods such as yogurt.) This usually occurs with plasmids, small circular molecules of DNA. This preview shows page 1 - 2 out of 3 pages. (Hint: one factor is in the plate and the other factor is in how you look at the bacteria). The growth of E. coli on the two plates could be compared. Colony size is similar both before and after transformation. The questions go in the same, order that they are asked in the PDF so make sure to answer these questions while you read, 1. Required Lab Report for BIO281. Fast production of offspring or new progeny will allow you to quickly assess if the new trait has been passed on. Duplication of any part of this document is permitted for classroom use only. Look again at your four plates. Cells which were treated with DNA (+pGLO) should contain the pGLO plasmid and should express the ampicillin resistance gene—the corresponding LB/amp plate will contain transformed bacterial colonies. Test. From the results that you obtained, how could you prove that these changes that occurred were due to the procedure that you performed? If there are any genetically transformed bacterial cells, on which plate(s) would they most likely be located? This experiment involved four different scenarios of bacterial cells on agar plates. The organism should grow vigorously in the lab environment, but should not be able to survive outside the laboratory. State the purpose of each component of the experiment, inhibits cell growth by interfering with cell wall synthesis, regulate Green Fluorescent Protein (GFP) expression in transformed cells, transforms bacteria that is used to make a cell competent, increases, possesses the ability to absorb blue light and in response show green, Substance that allows bacteria to recover before being plated. Bacteria transformation is the process of a bacterium absorbing and integrating naked DNA located on the surface of their membrane. Without bacteria, we would not be able to digest food or produce some of our favorite foods such as yogurt and cheese. 2017/2018. Flashcards. Test.
