the mutation above represents which type of mutation?
frameshift insertion
frameshift deletion
frameshift substitution
point substitution

Explanation:

Frameshift mutations occur when nucleotides are inserted or deleted, shifting the reading frame. Here, an extra nucleotide (C) is inserted (ATG→ACT), changing the sequence. Point substitution changes one base for another (no insertion/deletion). Frameshift deletion would remove a nucleotide. Frameshift substitution isn't a standard term. So, it's a frameshift insertion.

Answer:

Frameshift Insertion
