Further investigation of your cool alien life form reveals it contains a DNA polymerase that has an error rate of 1 mistake in every 106  bases copied. However, the overall mutation rate is much lower. This is most likely because:

Deamination of adenine produces hypoxanthine, which pairs with C.  What type of mutations would be induced by this event?    

Phosphorylation of the C-terminal domain tail of which protein serves as the timer and spatial organizer of eukaryotic transcription?

Which of the following are required for Base Excision Repair? (choose all that apply)

Which protein, when bound to DNA, introduces a 90 degree bend?

How do  prokaryotes ensure that they do not replicate their DNA more than once during each cell cycle?

You have recently discovered an alien life form and your research reveals that it has linear chromosomes with the following repeated sequence at the telomeres:  5’-TTAGGCATTAGGCA – 3’.  What sequence do you expect to find in the telomerase RNA?

Which of the following are required for Base Excision Repair? (choose all that apply)

The following table shows the probability P(x) of being stopped by a train x times in a month. x P(x) 0 0.021 1 0.035 2 0.764 3 0.140 4 0.040 Based on this table, is 1 an unusually low number of times to be stopped by a train in a month?  Support your answer using the values from the table.

A researcher asks 50 different random college students from the Twin Ports the number of hours they work each week.   a.  One of the requirements for the binomial probability distribution is that there must be a fixed number of trials.  Does the above procedure meet this condition?  Support your answer. b.  Another condition is that there must be two outcomes.  Does the above procedure meet this condition?  Support your answer. c.  (Extra Credit – 2 points) Another requirement is that selections must be independent.  Explain why this condition is satisfied.
