About Lesson
- The genetic code is ‘read’ in triplets of bases called codons. In other words, a set of three nucleotide bases constitutes a codon.
- In a triplet code, three RNA bases code for one amino acid.
- There are 64 codons which correspond to 20 amino acids and to signals for the initiation and termination of transcription.
- The code uses codons to make the amino acids that, in turn, constitute proteins.
- Each triplet [codon] specifies one amino acid in a protein structure or a start signal or stop signal in protein synthesis.
- The code establishes the relationship between the sequence of bases in nucleic acids (DNA and the complementary RNA) and the sequence of amino acids in proteins.
- The code explains the mechanism by which genetic information is stored in living organisms.
