During DNA replication in a bacterium, a C is accidentally incorporated instead of an A into one newly synthesized DNA strand. Imagine this error was not corrected and has no effect on the ability of the progeny to grow and reproduce. After this original bacterium divides once, fifty percent of its progeny contains the mutation. What proportion of its progeny would you expect to contain the mutation after three more rounds of DNA replication and cell division?



Options 1 : 50 %
2 : 25 %
3 : 12.5
4 : 6.25 %
Correct Option
2
