Each group of three bases in mRNA constitutes a codon, and each codon specifies a particular amino acid (hence, it is a triplet code). The mRNA sequence is thus used as a template to assemble—in order—the chain of amino acids that form a protein.
Each codon in mRNA is made up of three nucleotides, and each codon indicates a certain amino acid (hence, it is a triplet code). The mRNA sequence is therefore used as a template to construct the chain of amino acids that make up a protein in the correct order.
