WebMay 26, 2015 · This work demonstrates that maintaining the reading frame immediately after the initiation of translation by the ribosome is an essential aspect of protein synthesis. WebAn open reading frame (ORF) is a series of codons that begins with a start codon (usually AUG) and ends with a stop codon. There can be no additional stop codons within that sequence. In genes that lack introns (e.g. most prokaryotic genes), an ORF in the DNA sequence will define the entire translated region.

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.
