During DNA replication, the leading strand is synthesized continuously while the lagging strand is synthesized in Okazaki fragments. A mutation occurs in the gene encoding DNA ligase, reducing its activity by 90%. Additionally, primase function is slowed due to a chemical inhibitor. Which of the following best describes the expected consequences for DNA replication?

A research team discovers a mutation in the gene encoding a cyclin-dependent kinase (Cdk) that allows it to be constitutively active without cyclin binding. Additionally, this cell line has a nonfunctional p53 protein due to a separate mutation. During DNA replication in S phase, multiple errors occur due to exposure to UV radiation. Which of the following outcomes is most likely?

Researchers measured the rate of DNA synthesis in cells during different phases of the cell cycle. They used radioactive nucleotides to track DNA replication and measured incorporation rates over time. graph 3.jpg A mutation in DNA polymerase reduces its synthesis rate by 50%. At which time point would this mutation have the greatest impact on normal cell function?
