how many mitotic divisions are needed for a single cell to make 128 cells
Hi
Answer :- 7 times
EXPLANATION
In Mitosis a cell divides to produce two daughter cells.
So
In the 1st division, 1st cell produces 2 daughter cells
Then,
In the 2nd mitosis, 2 cells produces 4 daughter cells
In the 3rd mitosis, 4 cells give 8 daughter cells
In the 4th mitosis,8 cells give 16 daughter cells
In the 5th mitosis, 16 cells give 32 daughter cells
In the 6th mitosis, 32 cells give 64 daughter cells
In the 7th mitosis, 64 cells give 128 daughter cells
So, 7 mitotic divisions are required to produce 128 cells.
Short trick
Number of times of mitosis a cell will have to go through by the formula 2^n, where n = the no. of times the cell divides mitotically.
Then 2^n = 128
Or n = 7
Thank you
