Actually, to be a little more techical, an mRNA doesn’t always encode—provide instructions for—a whole protein. Instead, what we can confidently say is that it always encodes a polypeptide, or chain of amino acids.

WebPrimary proteins structure is simply the order of amino acids bound together by peptide bonds to make up a polypeptide chain.
