Question

Given that the average duplication time of E.coli is 20 minutes, how much time will two E.coli cells take to become 32 cells?

Answer 1

\[\ce{2 ->[I] 4 ->[II] 8->[III] 16->[IV] 32}\]

For the formation of 32 cells, two E.coli cells take 4 cycles. So the total time will be 4 × 20 = 80 minutes.
