|
Substitution

Deletion

Explanation:
Detailed explanation-1: -frameshift mutation because the change introduces an extra T near the beginning of the sequence. This will change the frame of the codons of the gene. The starting sequence of a gene changed from AUGTTCGACGTG to AUGTTTCGACGTG.
Detailed explanation-2: -A frameshift mutation in a gene refers to the insertion or deletion of nucleotide bases in numbers that are not multiples of three.
Detailed explanation-3: -A nonsense mutation occurs in DNA when a sequence change gives rise to a stop codon rather than a codon specifying an amino acid.
Detailed explanation-4: -Mutations can be of many types, such as substitution, deletion, insertion, and translocation.
