Question

Number of mitotic divisions required to produce 128 cells from a single cell __________.

• A. 7
• B. 14
• C. 16
• D. 32

Answer 1

The correct option is A 7

In mitosis, each cell divides into two. So starting from a single cell, the increase in a number of cells will occur as per the following progression- 1->2->4->8->16->32->64->128.

Thus a total of 7 divisions is required to produce 128 cells starting from a single cell or $2^n$ times the division.

So, the correct answer is option A.
