The building block of proteins.
A three-nucleotide sequence in an mRNA sequence. Used to specify an amino acid.
Term used to describe the genetic code. Means that more than one codon can specify for a single amino acid.
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.
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.
The series of codons that make up an organism's DNA.
A type of mutation that occurs within the genetic code to suppress a different 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.
An error in the genetic code caused most often by a the incorrect substitution, insertion, or deletion of a nucleotide.
One class of genetic code mutation that results from the substitution of one base group for another in a codon. Results in a stop codon, a codon that can no longer be recognized by tRNA molecules.
One of three possible ways of grouping an mRNA sequence by threes to yield an amino acid sequence.
A substitution base mutation that changes a codon, but because of degeneracy does not change the amino acid that codon specifies.
A codon that is not recognized by a tRNA molecule. One of three codons: UAA, UAG, or UGA. Signals the termination of DNA translation.
A type of genetic code mutation that alters the result of a different mutation. Can be either extragenic or intragenic.
Codons that code for the same amino acid.
One type of suppression mutation that leads to the restoration of the natural genetic code sequence.
