A codon is a trinucleotide sequence of DNA or RNA that corresponds to a specific amino acid. The genetic code describes the relationship between the sequence of DNA bases (A, C, G, and T) in a gene and the corresponding protein sequence that it encodes. The cell reads the sequence of the gene in groups of three bases.

WebJun 24, 2024 · An undergraduate student from India asks: “Why do we have three-base-codons when it is possible to translate four- or five-base-codons?”. DNA only has 4 different letters: A, T, C, and G. But a protein can have 20 different amino acids. This is where codons come in — they help translate the DNA code into a protein code. WebCodons provide the key that allows these two languages to be translated into each other.

They are found in tRNAs, and allow the tRNAs to bring the correct amino acid in line with an mRNA during protein production. During protein production, amino acids are bound together into a string, much like beads on a necklace.

WebThere are three more codons that do not specify amino acids. These stop codons, UAA, UAG, and UGA, tell the cell when a polypeptide is complete. All together, this collection of codon-amino acid relationships is called the genetic code, because it lets cells “decode” an mRNA into a chain of amino acids.
