Imagine that you start with a population of 10^6 E. coli, none of which carry any mutations in your gene of interest, which is 1000 nucleotides in length and not essential for bacterial growth and survival. In the next generaion, after the population doubles in number, what fraction of the cells, on average, would you expect to carry a mutation in your gene? After the population doubles again, what would you expect the frequency of mutants in the population to be? What would the frequency be after a third doubling? *** NOTE: This answer might be incorrect! ************************************************************** On 31.01.2017 (11:23) Isato wrote: I am not sure whether the answer s in the ex16_ecoli are correct... ******************************************************************************************************** gen0 = 0 gen1 = 1+2*gen0 = 1 of 2*10^6 gen2 = 1+2*gen1 = 3 of 4*10^6 gen3 = 1+2*gen2 = 7 of 8*10^6 *** NOTE: This answer might be incorrect! ************************************************************** On 31.01.2017 (11:23) Isato wrote: I am not sure whether the answer s in the ex16_ecoli are correct... ********************************************************************************************************
