A) DNA replication occurs only in mitosis.
B) DNA replication occurs only in meiosis.

Question

Quizplus · Accepted Answer

In meiosis, homologous chromosomes pair up and exchange genetic information through crossing over, resulting in genetically unique daughter cells. In contrast, mitosis results in genetically identical daughter cells since the replicated chromosomes are divided equally between the two daughter cells without crossing over. DNA replication occurs in both mitosis and meiosis. Option A and B are incorrect. Option D is incorrect because mitosis results in genetically identical daughter cells, except for rare mutations. Option E is incorrect because mitosis and meiosis are two distinct processes with different goals and outcomes.
