Answer:

two nucleotides are deleted

Explanation:

Frameshift mutations arise when the normal sequence of codons is disrupted by the insertion or deletion of one or more nucleotides, provided that the number of nucleotides added or removed is not a multiple of three.

Because two nucleotides are deleted (2 is not divisble by 3), it would be a source of a frameshift mutation.

Hope this helped! :^)
