What

Insertion

Explanation:

Mutation is generally referred to as any change or alteration that occurs to the nucleotide sequence of a gene. There are several types of mutation depending on how it occurs. The types of mutations are; substitution, insertion, deletion, etc.

Insertion mutation is a type of mutation in which one or more nucleotide base is added a sequence. This is the case in this question about an original sequence that reads: AGTATA. We then have the mutated sequence as follows: AGTATTA

Notice that, nucleotide "T" has been added in between T and A. Hence, a type of INSERTION mutation.
