- 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…Multiple Choice Question (suggested time - between 1 and 2 minutes): Which of the following is an element of a eukaryotic chromosome that plays an essential role in the replication of chromosomal ends?

There are two DNA helicases at each replication fork: one for the leading strand and one for the lagging strand. There are two sliding processivity clamps at each replication fork: one for the leading strand and one for the lagging strand. Primase synthesizes new primers made of DNA every -500-5000 nt on the lagging strand. The clamp loader complex (y) loads new sliding processivity clamps (B) every ~500-5000 nt on the lagging strand. The two DNA polymerase cores travel together in the same direction even though the two template DNA strands run 5'→3' in the opposite direction (antiparallel).Question 1 I .
