In meiosis, DNA replicates how many times?
AThree times
BFour times
COnce only
DTwice over
Answer & Solution
Correct answer: C. Once only
1. Replication happens in the S phase of interphase, before meiosis begins.
2. There is no second S phase between the two meiotic divisions.
3. During meiosis, DNA replicates once but divides twice, whereas in mitosis DNA replicates once but divides only once.
4. That single replication against two divisions is what halves the chromosome number.
