What is the mutation caused by the addition of a nucleotide to an already existing gene sequence called deletion duplication insertion inversionWhat is the mutation caused by the addition of a nucleot?

The mutation caused by the addition of a nucleotide to an existing gene sequence is called an "insertion." This type of mutation can disrupt the reading frame of the gene, potentially leading to significant changes in the resulting protein. If the insertion occurs within a coding region, it can alter the amino acid sequence and affect the protein's function.
