You start off with 100 E. coli cells known to divide every 20 minutes. Based on this information and using formulas for exponent
tensa zangetsu [6.8K]

Answer:

21 minutes or 0.35 hours

Explanation:

The formula for exponential population growth is

A = A_0* e^{kt}\\

where

A_0 = initial population of E.coli i.e 100

k is the rate of population growth i.e 2 as the population doubles

t is the time period i.e 20 minutes

Substituting the given values in above equation, we get -

A = 100 * e^{2 * \frac{20}{60} }\\\\A = 195

Generation time

G = \frac{t}{3.3 * log \frac{194}{100} } \\G = \frac{t}{0.949} \\G= 21 minutes

or 0.35 hours
