Question

Responses

three nucleotides are inserted
three nucleotides are inserted

three nucleotides are deleted
three nucleotides are deleted

two nucleotides are substituted
two nucleotides are substituted

two nucleotides are deleted

Answer 1

A frameshift mutation occurs when nucleotides are inserted or deleted from the DNA sequence in a number that is not a multiple of three. This disrupts the reading frame of the gene, leading to changes in the resulting protein.

Among the provided options, two nucleotides are deleted would result in a frameshift mutation.
