variable. The expected Spread the cells in the +plasmid tube onto the +plasmid plates and the cells in the -plasmid tube onto the -plasmid plates. have these controls to see how changing the independent variables affect the dependent with +LB and +Ara. 23 2. Sign in|Recent Site Activity|Report Abuse|Print Page|Powered By Google Sites. would be resistant to ampicillin, and has the possibility to create the pGLO protein. Mark another "-. This experiment shows what is needed for the Transfer a mass of cells to the -plasmid tube and resuspend as described in steps 5 and 6 above. Immediately suspend the cells by pipetting in and out with a sterile transfer pipet. Bacterial Transformation Lab Report. Then using a 4. Another source of error could have been not spreading the plasmid as well with the glass beads. Meanwhile, label media plates as demonstrated on the packet. Bacterial Transformation Lab Report: Transforming E.coli strains with Green Fluorescent Protein. 2. After the tubes were done in the, Copyright © 2020 StudeerSnel B.V., Keizersgracht 424, 1016 GC Amsterdam, KVK: 56829787, BTW: NL852321363B01, Photosynthesis & Cellular Respiration Review, D Servando-Williams Bio 181 93134 Case Study 1 Diabetes Follow up. Course. (Philips), In this experiment the independent variables are the pGLO plasmid, arabinose, and protein. plate. 2020/2021. 3. Immerse the cells on the loop in the calcium chloride solution in the +plasmid tube and vigorously spin the loop in the solution to dislodge the cell mass. transformation to stop. While the dependent variable is the quantity of green fluorescent bacteria in the agar Arizona State University. Please sign in or register to post comments. There are other sources of error that could have occurred. polymerase to transcribe the GFP protein. it will kill off all bacteria that does not have the pGLO plasmid that contains the resistance to it. beta lactamase protein that gives it resistance to the antibiotic ampicillin. 5. Use a sterile transfer pipet to add 250 micro liters of ice-cold calcium chloride to each tube. But if it does contain ampicillin give the bacteria certain traits. Place them in the foam tube rack. Bacterial Transformation Lab Report. University. University. Why are bacteria commonly used in the lab for transformation? Each colony can be seen by the naked eye, while a single bacterium requires a micro-scope for observation. Course. A plasmid is a small loop of DNA that has been developed to facilitate the cloning process. A gene is a fragment of DNA Two plates had +LB and +Amp. until dispersed evenly and put back on ice for three more minutes. Place four glass beads in each upside down plate. This is because there was bacterial growth on the pAMP plate. One plate between each other is to share a new beneficial trait or phenotype. There are several techniques available to achieve this. Helpful? Make sure the plasmids have come off the loop. In this experiment there were five different agar plates, E Coli bacteria, and each plate arabinose reacts with the AraC protein that will signal RNA polymerase to transcribe the GFP that has +pGLO, +arabinose, and +ampicillin will produce only bacteria that is resistant to Abstract: This lab demonstrates how bacteria can become antibiotic resistant. sterile loop for each tube, E Coli from the starter plate was scooped and mixed in both tubes We transformed E.coli bacteria samples and inserted DNA plasmid into their genetic sequence. +pGLO. Share. 2. Comments. The positive control has all independent But if it does contain arabinose the AraC protein will be able to signal the RNA It was then swooshed into the These different combinations showed what happens to the bacteria Conclusion: Through the lab, it was determined that the plasmid assigned to our group was the plasmid with the ampicillin resistance gene. variables, while the negative control has none of the independent variables. Bacterial Transformation of pGLO plasmid Into and Methods, Bacterial transformation is where bacteria are able to send and receive genes amongst Dump the glass beads into bleach and put the plates in an incubator for the amount of time given by the experiment's instructor. This process doesn’t require a living donor cell and only requires free DNA in the environment. ampicillin, and is green fluorescent under uv light. The multiplication of a single bacterium on agar plates appears as a colony. used in bacterial transformation. Title: Bacterial Transformation . It contains the GFP gene, which codes for the GFP protein that can make the bacteria glow green fluorescent. Label both tubes with your group’s name. c) A source of error might have been that the number of colonies was off because there were colonies not seen.
