Protein Synthesis - Overview
... The mRNA consists of nucleotides that code for a specific amino acid. The code is in triplet called a CODON (3 nucleotides = 1 amino acid). Amino acids are brought into place by a molecule known as transfer RNA (tRNA). This process is known as translation. Peptide bonds occur b/w amino acids. ...
