Conditional mutations are more likely to result from a mutation caused by which of the following alterations to the coding region of a gene?

Question

Quizplus · Accepted Answer

Tautomeric shifts can cause base-pair mismatches during DNA replication, which can lead to frameshift or missense mutations that may create conditional alleles (i.e. mutations that affect gene expression under specific conditions). The other options may also cause mutations, but they are less likely to result in conditional alleles.
