Answer:
A frameshift mutation.
Explanation:
A frameshift mutation is when one adds an extra nucleotide to a series of nucleotides. This will mess up the order of the nucleotide, thus when it forms the codons, and eventually, the amino acids; all of the codons are wrong, thus all of the amino acids are wrong.
In this situation, an extra nucleotide is added to a sequence of DNA, this results in all of the other nucleotides getting pushed over by (1). Thus, all of the nucleotides form the wrong codons and the wrong amino acids. Therefore, a frameshift mutation has occured.
