Start codon. The 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 a modified Met (fMet) in prokaryotes. The most common start codon is AUG.
A three-nucleotide sequence in mRNA that specifies a particular amino acid or polypeptide termination signal; basic unit of the genetic code. In translation, an mRNA codon is â¦ recognized by its complementary tRNA anti-codon. codon specifies a certain amino acid that makes up the protein. A codon is a sequence of three DNA or RNA nucleotides that corresponds with a specific amino acid or stop sig â¦ nal during protein synthesis.
