Question
Chapter 5, Problem 5.2.1AYLO
Summary Introduction
Interpretation:
The protein composition of hair and nail and its comparison with dominant epidermal protein to be determined.
Concept introduction:
Hair and nails are the appendages of the skin that had developed during the embryonic stages. They are formed from dead protein which adds the rigidity and resistance to the entire structure. It is the main protein component of epidermal layer of the skin.

a) What differences would you expect to see between the -DNA/+Amp and +DNA/+Amp plates?
b) Predict the growth you would expect to see on each of the following plates:
– DNA ___________________________________________________________
– DNA/+Amp ______________________________________________________
+DNA/+Amp ______________________________________________________
+DNA/+Amp/+IPTG _________________________________________________
1)Which plate did you see purple/pink/blue bacterial cells? Why did you see this growth? Explain your answer in terms of transformation and plasmids?
2) Calculating Transformation Efficiency
For the +DNA/+Amp/+IPTG plate, record the following:
Number of transformants (colonies): _________________
Nanograms of plasmid DNA added: 50 ng
Final recovery volume: 0.50 mL
Volume plated: 0.25 mL
Transformation efficiency equation:
Transformation efficiency = Number of transformants / µg of DNA x Final volume at recovery (mL)/ volume plated (mL)
3) Using the equation above, calculate the transformation efficiency.
4) Describe the success of the transformation efficiency of this demo based on the calculation you did above?
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?

In the reaction, OTMPD is electron acceptor O cytochrome c is the electron source oxygen is terminal electron acceptor OH2 produced is electron donorarrow_forwardYou 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. 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?

- Why are molecular approaches important to the field of microbial taxonomy and phylogeny?

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_forwardYou 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.
