8. DNA Replication

Which of the following proteins is responsible for unwinding the double stranded DNA?

DNA replication synthesizes DNA in which direction?

What would happen to DNA replication in DNA polymerase lost its 3' to 5' exonuclease activity?

Which of the following proteins is responsible for synthesizing RNA primers?

The short DNA fragments created during lagging strand replication are called what?

In the discussion, we focused on how DNA is replicated and synthesized. We also discussed recombination at the DNA level. Along the way, we encountered many opportunities to consider how this information was acquired. On the basis of these discussions, what answers would you propose to the following fundamental questions?

What observations reveal that a 'telomere problem' exists during eukaryotic DNA replication, and how did we learn of the solution to this problem?

In the discussion, we focused on how DNA is replicated and synthesized. We also discussed recombination at the DNA level. Along the way, we encountered many opportunities to consider how this information was acquired. On the basis of these discussions, what answers would you propose to the following fundamental questions?

How do we know that DNA synthesis is discontinuous on one of the two template strands?

In the discussion, we focused on how DNA is replicated and synthesized. We also discussed recombination at the DNA level. Along the way, we encountered many opportunities to consider how this information was acquired. On the basis of these discussions, what answers would you propose to the following fundamental questions?

How do we know that in vivo DNA synthesis occurs in the 5' to 3' direction?

In the discussion, we focused on how DNA is replicated and synthesized. We also discussed recombination at the DNA level. Along the way, we encountered many opportunities to consider how this information was acquired. On the basis of these discussions, what answers would you propose to the following fundamental questions?

How was it demonstrated that DNA synthesis occurs under the direction of DNA polymerase III and not polymerase I?

Write a short essay that distinguishes between the terms replication and synthesis, as applied to DNA. Which of the two is most closely allied with the field of biochemistry?

Compare conservative, semiconservative, and dispersive modes of DNA replication.

Describe the role of ¹⁵N in the Meselson–Stahl experiment.
