1) Look at the ideal results. Were your predictions accurate, and how did they compare with your results?
2) You used aseptic technique during this lab. Why is it important to work in a sterile manner when working with bacteria in the lab?
3) Why are the cells incubated at 42°C?
Overview of Transformation Protocol
-Prepare competent bacteria for transformation:
Treat starter E. coli bacteria with CaCl2and Competent Cell Solution (CCS). Store on ice until transformation procedure.
Competent cells are cells that are likely to take up foreign DNA and be transformed. This step increases the likelihood that the E. coli cells will take up the introduced vector and be transformed.
-Transformation procedure:
Obtain two microcentrifuge tubes containing your competent cells. Label one tube +DNA and one -DNA.
Add CaCl2 to both tubes.
Add the transformation mix containing the plasmid DNA to the tube labeled +DNA. Do not add any plasmid DNA to the -DNA tube.
Incubate both tubes on ice for 10 minutes. Then, place both tubes in a 42\deg C water bath for 45 seconds. Replace the tubes in an ice bucket for 2 minutes.
Add recovery broth to both tubes.
Incubate both tubes in a 37 C water bath for 5 minutes.

You have isolated a microbe from an environmental sample. The microbe has the ability to perform a new metabolic reaction at a very low temperature, so you are excited that it could be a new species. You have shipped your samples off for sequencing and are now waiting for the results. Out of curiosity (and maybe boredom...) you decide to test your culture for the Catalase and Oxidase enzymes. Upon testing your sample for catalase, you don't see any bubbles; however, you do see a color change to purple during the Oxidase test. What results can you conclude from this?

Phylogenetic inferences based on molecular approaches provide the most robust analysis of microbial evolution currently available.

You have isolated a microbe from an environmental sample. The microbe has the ability to perform a new metabolic reaction at a very low temperature, so you are excited that it could be a new species. You have already cultured it and gone through the plate isolation procedure. Before you ship your samples off for sequencing, you want to do one final check of the A260 ratios. You get back the following ratios: A260/280 ratio is 1.89; A260/230 is 2.01. These ratios are close enough to the accepted "pure" values so they could be considered "pure" and mostly (if not completely) free of contaminants from the PCR process. True Falsearrow_forward
- You will use the following scenario to answer a group of 5 questions. You have isolated a microbe from an environmental sample. The microbe has the ability to perform a new metabolic reaction at a very low temperature, so you are excited that it could be a new species. After receiving your sequence back from the sequencing lab, you feel that you have, in fact, discovered and isolated a new species. You ask a fellow labmate about how you should proceed, and he tells you the following is the proper way to introduce a new species for recognition: Cultures have to be sent to international culture collections. Then a paper must be published describing the new organism and providing a genus and species name. You recall learning about this in your Microbiology course in college. Is this information from your colleague true or false? True Falsearrow_forwardis often a good indication of phylogenetic relatedness in phenotypes.
