WebThe start codon is the first codon of a messenger RNA (mRNA) transcript translated by a ribosome.The start codon always codes for methionine in eukaryotes and Archaea and a N-formylmethionine in bacteria, mitochondria and plastids.The most common start codon is AUG (i.e., ATG in the corresponding DNA sequence). The start codon is often preceded … http://www.columbia.edu/cu/biology/courses/c3032/answers-4.html

A codon table can be used to translate a genetic code into a sequence of amino acids. The standard genetic code is traditionally represented as an RNA codon table, because when proteins are made in a cell by ribosomes, it is messenger RNA (mRNA) that directs protein synthesis. The mRNA sequence is … See more The genetic code was once believed to be universal: a codon would code for the same amino acid regardless of the organism or source. However, it is now agreed that the genetic code evolves, resulting in … See more • Biology portal • Evolutionary biology portal • Bioinformatics • List of genetic codes See more • DNA codon chart organized in a wheel See more • Chevance FV, Hughes KT (2 May 2024).
