Question

How many mitotic divisions are required to produce 128 cells from a single cell?

• A. 16
• B. 8
• C. 14
• D. 7

Answer 1

The correct option is D 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 D.
