| Frameshift mutation | type of mutation in the amino acid sequence due to the addition or deletion of one (or more) DNA nucleotide (s) |
| mutation | any change in the sequence of nucletoides in DNA |
| RNA Polymerase | en enzyme which transcribes DNA nucleotide sequence into RNA nucleotide sequence |
