Question

A μtational event inserts an extra nucleotide into DNA. Which of the following outcomes do you expect?

a) Silent μtation
b) Frameshift μtation
c) Missense μtation
d) Nonsense μtation

Answer 1

A μtational event that inserts an extra nucleotide into DNA would result in a frameshift mutation.

Step-by-step explanation:

A μtational event that inserts an extra nucleotide into DNA would result in a frameshift mutation. Frameshift mutations occur when the reading frame of the base sequence is altered by the insertion or deletion of one or more nucleotides. In this case, the insertion of an extra nucleotide shifts the reading frame, leading to changes in every subsequent codon. This type of mutation can have significant consequences and may create premature stop codons, resulting in truncated or non-functional protein products.
