Insertions And Deletions Shift The Reading Frame

Insertions add extra nucleotides into the DNA sequence.
Deletions remove nucleotides from the DNA sequence.
Both can disrupt the genetic code, often more severely than a substitution.

Frameshift Mutations: A Domino Effect

DNA is read in triplets called codons, each coding for one amino acid.
Adding or removing bases in a number that is not a multiple of three shifts the reading frame, altering every codon downstream.
