A frameshift mutation is a type of genetic mutation that involves the insertion or deletion of nucleotides in a DNA sequence. This mutation can cause a shift in the reading frame of the genetic code, leading to a change in the amino acid sequence of the resulting protein. This can have significant effects and often lead to a nonfunctional or partially functional protein. Frameshift mutations can occur spontaneously or be caused by mutagens, and they can have serious consequences for an organism, potentially leading to genetic disorders or diseases.
