Question

How many mitotic divisions are needed for a single cell to make 128 cells?

• A. 7
• B. 14
• C. 28
• D. 6

Answer 1

The correct option is (A):

Explanation of the correct option:

1. ​A single cell produces two daughter cells during mitosis.
   
2. This is why for determining the number of cells after specific cycles of mitotic division in the cell be determined using the value of $2^n$ .
3. The value of 'n' here is the number of cycles of mitosis taking place in all cells.
   
4. The final number of cells produced through mitosis is given here as 128.
   
5. If the given formula is chosen, it shows that $2^7=128$ .
   
6. Therefore the value of n is 7, which means 7 cycles of mitotic division are taking place resulting in 128 cells from a single cell.
   

Final Answer: 7 mitotic divisions are needed for a single cell to make 128 cells
