Explanation
The addition of one or a few bases into a DNA sequence is called an insertion mutation. This type of mutation involves the addition of extra nucleotides into the DNA sequence, which can lead to a shift in the reading frame during translation, potentially resulting in a completely different amino acid sequence and protein product.
