Dna sequence for methionine

WebAll protein-coding regions begin with the sequence "ATG," which encodes the amino acid methionine (Met). Therefore, the correct reading frame will contain the codon "ATG." You can predict the amino acid sequence of the protein by using the Universal Genetic Code. Why isn't the start codon in DNA complementary to AUG? In the standard code, the sequence AUG—read as methionine—can serve as a start codon and, along with sequences such as an initiation factor, initiates translation. [3] [8] [9] In rare instances, start codons in the standard code may also include GUG or UUG; these codons normally represent valine and leucine , … See more 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 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 discrepancies in how a codon is translated … See more • DNA codon chart organized in a wheel See more • Biology portal • Evolutionary biology portal • Bioinformatics • List of genetic codes See more • Chevance FV, Hughes KT (2 May 2024).
