Frameshift Mutations
Frameshift mutations result from the insertion or deletion of nucleotides in a DNA sequence, causing a shift in the reading frame during translation. This alteration disrupts the codon reading pattern, leading to the production of a completely different amino acid sequence. Frameshift mutations can have significant effects on protein structure and function, often resulting in nonfunctional or truncated proteins. These mutations can be spontaneous or induced by mutagens, and are associated with a variety of genetic disorders and diseases.
