These small single stranded RNA molecules fold back on themselves to generate a compact L-shaped structure. In the bacterium E. coli, there are 87 genes that encode tRNAs (there are over 400 such tRNA encoding genes in human). For each amino acid and each codon there are one … WebEach amino acid is brought to the ribosome by a charged tRNA, which pairs with the codon on the mRNA through base pairing between the anticodon on the tRNA and the codon on the mRNA. Peptide bonds are formed between adjacent amino acids, catalyzed by the ribosome, and the ribosome moves along the mRNA to expose the next codon. termos air panas tahan 2 hari
