Natural selection is such a powerful force, Biology

Assignment Help:

Natural selection is such a powerful force in evolution because cells with even a small growth advantage quickly outgrow their competitors. To illustrate this process, consider a bacterial culture that contains 106 (1,000,000) cells that double every 64 min. One cell acquires a mutation that enable it and its progeny to divide with a generation time of only 30 min. Assuming there is nothing to limit the growth of the culture (e.g. unlimited food supply) and no cell death, how long should it take for the mutant cells to overtake the culture? Give your rounded answers in minutes (min). The number of cells N in the culture at time t is given by N=N02t/G where N0 is the number of cells at time zero and G is the generation
