Homologous recombination occurs directly after DNA replication?
A
True
B
False
Verified step by step guidance1
Understand the context of homologous recombination: It is a process that involves the exchange of genetic material between homologous DNA molecules, which are similar or identical in sequence.
Recognize the timing of DNA replication: DNA replication occurs during the S phase of the cell cycle, where the DNA is duplicated to ensure that each daughter cell receives an identical set of chromosomes.
Identify when homologous recombination typically occurs: Homologous recombination is most active during the late S and G2 phases of the cell cycle, after DNA replication has occurred.
Consider the purpose of homologous recombination: It is crucial for repairing double-strand breaks in DNA and ensuring genetic diversity during meiosis.
Conclude based on the timing: Since homologous recombination occurs after DNA replication, the statement 'Homologous recombination occurs directly after DNA replication' is true.
