Question

How many times a cell will have no divide mitotically, to form $128$ cells?

• A. $7$
• B. $14$
• C. $28$
• D. $32$

Answer 1

The correct option is A $7$

Answer :

i) Mitosis is an equational division process and it produces two daughter cells from the single parent cells.
ii) Clearly, the formula (2)^n would answer the number of cells produced, where n would be the number of divisions.

(2)^n = 128

(2)^n = (2)^7, Therefore, n=7.

iii) It will take 7 divisions to produce 128 cells from a singe cell by mitosis.

So correct answer is option A. 7.
