Question

Which of the following statement is correct regarding meiosis?

• A. Division of nucleus twice but replication of DNA only once
• B. Division of nucleus is twice and replication of DNA twice
• C. Division of nucleus once and replication of DNA is also once
• D. Division of nucleus once and DNA replication is twice

Answer 1

The correct option is A Division of nucleus twice but replication of DNA only once

In meiosis, division of nucleus twice but replication of DNA only once. In meiosis, DNA replication is followed by two rounds of cell division to produce four daughter cells with half the number of chromosomes as the original parent cell. The two meiotic divisions are known as meiosis I and meiosis II. Before meiosis begins, during S phase of the cell cycle, the DNA of each chromosome is replicated so that it consists of two identical sister chromatids attached at a centromere.

So, the correct answer is option A.
