Which of the following statement is correct regarding meiosis?

ADivision of nucleus twice but replication of DNA only once
Correct Answer
BDivision of nucleus is twice and replication of DNA twice
CDivision of nucleus once and replication of DNA is also once
DDivision of nucleus once and DNA replication is twice

Solution

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.
