Web17. What is a reading frame, as it relates to a gene sequence? A reading frame is the sequence of three-base subunits (or codons) that the ribosome processes and translates sequentially into amino acids according to the universal genetic code. The open reading frame (ORF) is the protein-coding region of each mRNA. The reading frame begins with a … The usage of multiple reading frames leads to the possibility of overlapping genes; there may be many of these in viral, prokaryote, and mitochondrial genomes. Some viruses, e.g. hepatitis B virus and BYDV, use several overlapping genes in different reading frames.
