Question

The significance of mitosis is to keep the chromosome number constant in a species.

• A. True
• B. False

Answer 1

The correct option is A True

1. In mitosis cell division, the resulting two daughter cells always contain the same number of chromosomes as the parent cell from which they originated.
2. Their role is to maintain a constant number of chromosomes in each cell division, enabling us to grow our bodies and take care of ourselves.
3. Thus, in a mitotic cell cycle, the DNA content of each chromosome doubles at the S stage (each chromosome begins as a chromatid and then becomes a similar sister chromatid at the S stage), but the chromosome number remains the same.

The given statement is True.
