Question

if a bacterium has a generation time of 30 minutes and you start with 100 cells at time 0, how many cells will you have in 30 minutes

Answer 1

The time taken by the bacteria to double in number during a period of certain time is the generation time.

We will have 200 cells: bacteria will divide once during 30 minutes, so number

of the cells will be 100x2 = 200 cells.
