Question

A cell has 5 pairs of chromosomes. After mitotic division, the number of chromosomes in daughter cells will be

• A. 5
• B. 10
• C. 20
• D. 40

Answer 1

The correct option is B

10

The correct option is B.

The explanation of the correct option:

1. Mitosis is a process that occurs in all cells in the body except reproductive cells.
2. The number of chromosomes in the daughter cells remains the same (i.e., diploid 2n). Hence, it is called equational division.
3. If a diploid cell is divided by mitosis, the products are diploid.
4. Mitosis results in the formation of two daughter cells.
5. Prophase, Metaphase, Anaphase, and Telophase are the four stages of Mitosis.

Diploid Number

1. A cell with a diploid number has two copies of each chromosome.
2. The number of pairs of diploid chromosomes is denoted as 2n.
3. Human body cells, for example, have 46 (2n) or 23 pairs of chromosomes.

Here, the parent cell has five pairs or ten chromosomes. So, the daughter cells will have ten chromosomes after Mitosis.

Final answer: A cell has 5 pairs of chromosomes. After mitotic division, the number of chromosomes in daughter cells will be 10.
