WebThe ribosome is universally responsible for synthesizing proteins by translating the genetic code transcribed in mRNA into an amino acid sequence. Ribosomes use cellular accessory proteins, soluble transfer RNAs, and metabolic energy to accomplish the initiation, elongation, and termination of peptide synthesis. 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. microsoft office 365 makro
