Question

If in a cell culture, starting from a single cell, 4096 cells are formed in 6 days then the average time duration of one cell cycle is :

• A. 6 hours
• B. 12 hours
• C. 24 hours
• D. 3 hours

Answer 1

The correct option is B 12 hours

In a cell culture medium, starting from a single cell.

We know that, after every cycle cells become twice in number.

Therefore,

$1\stackrel{x}{\to }2\stackrel{x}{\to }4\stackrel{x}{\to }8\stackrel{x}{\to }16\stackrel{x}{\to }...4096$

$x=$time taken by one cycle

Total cycle, $2^{12}=4096$

from the calculation will be $12$.

Total given time is $6$ days

Therefore, time duration for $1$ cycle will be $12$ hours.

Also, $12$ cycle$=$In $6$ days

$1$ cycle$=\frac{6\times 24}{12}$ hours

$1$ cycle$=12$ hours

Therefore, the option (B) is correct.
