Exercise 4

During replication, an error uncorrected by proofreading or mismatch repair produces a DNA molecule with a base mismatch at the indicated position: 11eb5caa_282f_34c5_9f04_edf01d902d6e
The mismatch results in a mutation.This DNA molecule is received by one of the two daughter cells produced by mitosis.In the next round of replication and division, the mutation appears in only one of the two daughter cells.Develop a hypothesis to explain this observation.
