An insertion mutation is a type of genetic alteration where one or more nucleotide bases are added into the DNA sequence of a gene. This can disrupt the normal reading frame of the gene, potentially leading to significant changes in the resulting protein. Insertion mutations can occur naturally during DNA replication or be induced by external factors, and they play a crucial role in genetic diversity and evolution, as well as in the development of certain diseases.
