Quizplus · Accepted Answer

If a DNA replication error is not corrected, the mutation will be present in one of the two strands of the DNA. After the first cell division, one daughter cell will have the mutation, and the other will not. After the second cell division, the mutation will be present in two of the four daughter cells.
