Science / Biology / Anticodon: A sequence of three nucleotides on the transfer RNA molecule that recognizes and pairs with a specific codon on a messenger RNA molecule; helps control the sequence of amino acids in a growing polypep MORE
Science / Genetics / Degenerate Codon: A codon that specifies the same amino acid as another codon. MORE
Science / Biology / Thecodonts: An informal term for a variety of Permian and Triassic reptiles that had teeth set in individual sockets. Small, bipedal thecodontians are the probable ancestors of dinosaurs. MORE
Science / Biology / Stop Codon: The codon on a messenger RNA molecule where protein synthesis stops. MORE
Science / Biology / Start Codon: The codon (AUG) on a messenger RNA molecule where protein synthesis begins. MORE
Science / Biology / Termination Codon: One of three three-base sequences that initiate termination of the protein synthesis process. See stop codon. MORE
