14.6: DNA Repair. DNA replication is a highly accurate process, but mistakes can occasionally occur, such as a DNA polymerase inserting a wrong base. Uncorrected mistakes may sometimes lead to serious consequences, such as cancer. Repair mechanisms correct the mistakes.
Consider the replication of a circular viral DNA in infected cells. The infected cells were pulse labeled with [3H] thymidine for 1, 2, 3 and 4 min; it takes 4 min for the DNA molecules to be replicated in this system (from initiation to termination).
8 de ago. de 2024 · Challenge yourself with questions about the structure of DNA, the roles of DNA polymerase and helicase, and the significance of replication forks. Delve into the complexities of leading and lagging strand synthesis, Okazaki fragments, and the proofreading mechanisms that ensure genetic fidelity.
DNA is extracted after each generation and analyzed on a CsCl gradient. From the results shown below, what is the mode of replication in B. mulligan ? Explain your conclusion.
Complete the following vocabulary exercise related to DNA replication. 1. During DNA replication, an open section of DNA, in which a DNA polymerase can replicate DNA, is called a replication fork.
DNA replication results in two identical daughter molecules each consisting of one old (original) strand and one newly-synthesized strand. A) True: B) False
