Question

In meiosis, homologous recombination (crossing over) could theoretically take place before, during, or after DNA synthesis. Cytological, biochemical, and genetic evidence indicates that it takes place in prophase I of meiosis, whereas DNA replication takes place earlier, in interphase.

A) True
B) False

Answer 1

Homologous recombination takes place during prophase I of meiosis, while DNA replication occurs earlier in interphase.

Step-by-step explanation:

True

In meiosis, homologous recombination (crossing over) takes place during prophase I. During this phase, homologous chromosomes line up together and exchange genetic material, resulting in new combinations of genes on each chromosome. DNA replication, on the other hand, occurs earlier in interphase.
