"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. " - Reading frame in protein synthesis

WebJan 1, 2024 · Maintenance of translational reading frame ensures the fidelity of information transfer during protein synthesis. Yet, programmed ribosomal frameshifting sequences within the coding region promote a high rate of reading frame change at predetermined sites thus enriching genomic information density.

An open reading frame (ORF) is a reading frame that has the potential to be transcribed into RNA and translated into protein. It requires a continuous sequence of DNA from a start codon, through a subsequent region which usually has a length that is a multiple of 3 nucleotides, to a stop codon in the same reading frame.
