Codon: It is a three-nucleotide sequence that codes for a specific amino acid or a stop signal during protein synthesis.
- The genetic code explains the relationship between a gene's sequence of DNA bases (A, C, G, and T) and the protein sequence encoded by the codon.
- Codons are the key that allows DNA nucleotide sequences to be translated into protein amino acid sequences and vice versa.
- Each codon corresponds to a single amino acid or a stop signal, and the entire set of codons is referred to as the genetic code.
- When it comes to protein synthesis, CAU is the genetic code for the histidine amino acid.
