Genetic Code Terms Amino Acid - The building block of proteins. Codon - A three-nucleotide sequence in an mRNA sequence. Used to specify an amino acid. Degenerate - Term used to describe the genetic code. Means that more than one codon can specify for a single amino acid. Extragenic supression - A type of mutation that occurs outside of the genetic code, but has an effect on the amino acid sequence that is translated from the genetic code. Frameshift mutation - One class of genetic code mutation that results from the insertion or deletion of a nucleotide to an mRNA sequence. Results in a new reading frame. Genetic Code - The series of codons that make up an organism's DNA. Intragenic suppression - A type of mutation that occurs within the genetic code to suppress a different mutation. Missense mutation - One class of genetic code mutation that results from the substitution of one base group for another in a codon. Results in the change of the amino acid for which the codon specifies.
