True or False: In this trial (Hershey And Chase), since labeled viral proteins were found outside the living cell, they concluded that proteins must carry at least part of the genetic information in the virus.

Question 1: Look at the following normal and mutant DNA sequences. Normal Sequence (5'-3'): ATG AAC GTT ATC GCA Mutated Sequence (5'-3'): ATG AAT GTC ATC GCA a) What type of mutation has occurred (be specific)? b) Fill in the table for the normal and mutated sequences. Starting with the given 5'-3' sequence, input the complementary DNA, transcribed RNA from the 3'-5' DNA and translated polypeptide sequence for both. Hint: use the codon table! Normal sequence Mutant sequence DNA 5'-3' (given) DNA 3'-5' RNA Polypeptide (use 3 letter codes) c) Based on parts A and B above, what is the ultimate effect this mutation has had on the polypeptide?

Question 2. For your senior research, you end up studying the life cycle of an animal virus whose genome consists of a single circular, double-stranded DNA molecule. Your project is to define the number and location of the origin(s) of replication and to determine whether replication proceeds in one (unidirectional) or both (bidirectional) directions away from an origin. To accomplish this, you isolate many identical strands of DNA that have already been partially replicated. You cleave each piece of DNA exactly once with a restriction enzyme. You then observe the cut pieces of DNA using an electron microscope. Below is a schematic representation of what you observe. Remember that each line represents a different piece of DNA, and not a fragment of a larger piece. Using this data, answer the following questions: A) How many origins of replication do you think the viral genome has, and why do you think this? 30: F2 #3 *** E D 80 F3 54 $ 4 F4 R LL % 5 F5 T G B) Do your data support…
