There are 64 different codons in the genetic code and the below tables; most specify an amino acid. [6] . Three sequences, UAG, UGA, and UAA, known as stop codons, [note 1] do not code for an amino acid but instead signal the release of the nascent polypeptide from the ribosome. [7] .

Listed below are the amino acids that would have been needed to be inserted to continue the wild-type chain and their codons: In each case, the codon marked by an asterisk would require a single base change to become UAG. 9. a. The codons for phenylalanine are UUU and UUC. Only the UUU codon can exist with randomly positioned A and U.

Tool to translate DNA/RNA codons. A codon is a group of 3 nucleotides A, C, G, T, U. Codons are extracted from RNA or DNA (genetic code).

In order to translate an mRNA sequence into a polypeptide chain, it is important to establish the correct reading frame. The mRNA transcript is organised into triplets of bases called codons, and as such three different reading frames exists.
