While the specific nucleotide sequence of an mRNA specifies which amino acids are incorporated into the protein product of the gene from which the mRNA is transcribed, the role of tRNA is to specify which sequence from the genetic code corresponds to which amino acid. The mRNA encodes a protein as a series of contiguous codons, each of which is recognized by a particular tRNA. One end of the tRNA matches the genetic code in a three-nucleotide sequence called the a… WebIn 1D, the eukaryotic and archaeal pathway for Sec-tRNA biosynthesis is shown; in bacteria, a single enzyme, SelA, carries out the conversion of Ser to Sec, as indicated by the arrow below.
