A frameshift mutation (also called a framing error or a reading frame shift) is a genetic mutation caused by indels (insertions or deletions) of a number of nucleotides in a DNA sequence that is not divisible by three.
Both frameshift and point mutations are such alterations in the nucleotide sequence of a gene. However, the two types vary from each other in many ways, despite the result is a changed gene; hence, a different phenotype could be expressed eventually. Frameshift Mutation.
