Without a well … WebAug 7, 2024 · For any given mRNA sequence, there are three possible reading frames (1, 2, and 3). B. An AUG near the 5′-end of the mRNA (the start codon) sets the reading frame for the translation of a protein from the mRNA. The codons are read in linear order, starting with this AUG. (The other potential reading frames are not used.
