Each trna molecule is bound to a specific

WebEach tRNA contains a set of three nucleotides called an anticodon. The anticodon of a given tRNA can bind to one or a few specific mRNA codons. The tRNA molecule also carries an amino acid: specifically, the one encoded by the codons that the tRNA binds. … The A site accepts an incoming tRNA bound to an amino acid. The P site … WebBrief history. In the genetic code, there are 4 3 = 64 possible codons (3 nucleotide sequences). For translation, each of these codons requires a tRNA molecule with an anticodon with which it can stably complement. If each tRNA molecule is paired with its complementary mRNA codon using canonical Watson-Crick base pairing, then 64 types …
