the mRNA has its introns removed by a complex called what?

A codon is composed of how many nitrogen bases?

When a tRNA is empty, it is release from what active site?

  Above is an indole dry slide with the results for two different bacteria, microbe A (red color) and microbe B (yellow color). Which one of the microbes is “indole positive” and which enzyme does this microbe make that permits it to make indole?

   Above are urease tests for two bacteria, microbe A and microbe B.   A= microbe A B= microbe B C= uninoculated control

You inoculate a bacterium into PR Glucose.  The bacterium then ferments the glucose. What color will the medium be and why?

Above is a photo of PR Sugar broths. What does “PR” mean and what is the name of the inverted tube?

Which pH indicator: test pair below is incorrect/false?  (0.5 points) a. phenol red: TSI b. bromothymol blue: indole c. methyl red: MR test d. bromothymol blue: Simmon’s citrate test

In our studies of bacterial metabolism, E. coli was able to ferment glucose, lactose, and sucrose.  But, Pseudomonas fluorescens was not able to ferment any of these sugars. Briefly explain why these two organisms have such different metabolic capabilities.  Hint:  the answer is really simple, so don’t overthink it.
