WebThe ribosome moves along the mRNA from the 5' end to the 3' end, reading the codons and helping the amino acids form peptide bonds. The amino acid is moved from the tRNA in the A site of the ribosome to the tRNA in the P site, which is carrying the growing polypeptide chain. This is how peptide bonds are made. Transfer RNA (abbreviated tRNA and formerly referred to as sRNA, for soluble RNA ) is an adaptor molecule composed of RNA, typically 76 to 90 nucleotides in length (in eukaryotes), that serves as the physical link between the mRNA and the amino acid sequence of proteins. tRNAs genes from Bacteria are typically shorter (mean = 77.6 bp) than tRNAs from Archaea (mean = 83.1 bp) and euka…
