Question

Number of mitotic division required for formation of $128$ cells.

• A. $127$
• B. $32$
• C. $12$
• D. $64$

Answer 1

The correct option is A $127$

It will require 127 mitotic divisions to occur to produce 128 cells from one cell provided none of the cell lysed in the process. First mitotic division would form two daughter cell. Each of these two daughter cells then undergoes division to form four cells after 1+2=3 divisions.

Hence A is the correct option.
