WebThe approximately 271-nucleotide body region of the M2 mRNA can be translated in the +1 reading frame, and the sequence indicates that M1 and M2 overlap by 14 amino … WebDuring translation, a cell “reads” the information in a messenger RNA (mRNA) and uses it to build a protein. 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.
