a flask is inoculated to density of 3 x 10 * cells /ml ( * is 3.i.e 10 to the power of 3) .what is the density of cells in culture after 50 min if generation time is 20 min and lag time is 10 min ?

  #2

3 X 10 * with 3 doubling times = 2.4 X 10 * (where * = 4)

or...24000

  #3

3 X 10 * with 2 doubling times = 1.2 X 10 * (where * = 4)

or...12000

  #4
