Question

How many mitotic divisions are needed for a single cell to make 256 cells?

• A. 8
• B. 16
• C. 32
• D. 64

Answer 1

The correct option is A 8

Mitosis is an equational cell division. The diploid offspring are formed by mitosis of the diploid somatic parent cell. After each mitotic division two cells are formed, i.e., the number doubles every time. So, the number of cells formed after each division is given by 2${}^n$. 256 can be given by 2${}^8$. Eight mitotic divisions are needed to make 256 cells.

So, the correct answer is option A.
