DictionarySeeframeshift mutationreading-frameshift mutation
read·ing-·frame·shift mu·ta·tiona mutation that results from insertion or deletion of a single nucleotide into, or from, the normal DNA sequence; because the genetic code is read three nucleotides at a time, all nucleotide triplets distal to the mutation will be one step out of phase and misread, and hence translated as different amino acids. Synonym(s): addition mutation, addition-deletion mutation, deletion mutation, frameshift mutation |
