How do codons work

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. WebSep 13, 2024 · Codons are a triplet of adjacent nucleotides in the messenger RNA chain that codes for a specific amino acid in the synthesis of a protein molecule. What does a codon consist of quizlet? A codon is a group of three bases that can specify more than one amino acid. A codon is a group of three bases that can specify only one amino acid.
