Reading frame biology

WebWhat is an open reading frame (ORF)? It is the part of a reading frame that codes for the gene. Starting with a start codon (usually ATG but not always) and ending with a stop codon (TAA, TAG or TGA in most genomes) WebWell the open reading frame would be the sequence that contains no stop codon and is read by the polymerase and subsequently by the ribosome to form the protein. A reading frame in itself is just a sequence of nucleotides, cut into codons. All sequences will have 3 different reading frames.
