1.Initiation: mRNA attaches itself to the ribosome; the first codon in the mRNA is always AUG (initiation codon-start sequence), which codes for methionine; tRNA brings in the first amino acid (methionine) and places it in its proper place.
- 2.Elongation: Subsequent amino acids are brought to the ribosome and bonded
- together with a peptide bond.
3.Termination: There are three codons which are known as stop codons (UAA, UAG, UGA). These serve as the signal to stop protein synthesis and release the protein from the ribosome.
