Question

The replication of DNA in meiosis occur during

• A. S phase
• B. S phase and leptotene
• C. S phase and zygotene
• D. All of the above

Answer 1

Answer: (A)

S phase

The replication of DNA in meiosis occur during S phase. S phase or the synthesis phase is the part of the cell cycle in which DNA is replicated, occurring between G${}_1$ phase and G${}_2$ phase. S Phase occurs to produce two similar daughter cells, the complete DNA instructions in the cell must be duplicated. DNA replication occurs during this S or synthesis phase.

So, the correct answer is option A.
