Question

DNA synthesis during Cleavage is

• A. Faster than typical mitosis
• B. Slower than typical mitosis
• C. DNA synthesis does not occur
• D. Depends on other factors

Answer 1

Answer: (A)

Faster than typical mitosis

Cleavage is the term used for repeated mitotic divisions that take place during the growth of an embryo. No actual growth occurs during this process as the initial and final stages are of almost the same size of almost the same size. During this process, the whole DNA genome of the embryo divides at a rate 60 times faster than the normal pace of DNA replication in a somatic cell.

So, the correct answer is 'Faster than typical mitosis'.
