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. WebSince the process of DNA-directed protein synthesis was discovered, scientists and philosophers have searched, more or less seriously, for a relationship between the triplet nucleic acid codons and the chemical nature of the amino acids. ...
