B) DNA replication occurs only in meiosis and not in mitosis.

Question

Quizplus · Accepted Answer

During meiosis, homologous chromosomes pair up, exchange genetic material, and then separate, resulting in four genetically diverse daughter cells. In contrast, during mitosis, a single cell divides into two genetically identical daughter cells. DNA replication occurs in both mitosis and meiosis, so choices A and B are incorrect. Choice D is also incorrect because meiosis produces genetically diverse daughter cells. Choice E is completely false as mitosis and meiosis are fundamentally different processes.
