Answer & Explanation:
In the genetic code, sequences of three nucleotides, called codons, serve as the code for amino acids. Each codon represents a specific amino acid, and when these codons are read in the correct order, they specify the sequence of amino acids in a protein. Codons also have other roles in the genetic code, such as signaling the start and end of transcription and translation. For example, the codon AUG signals the start of transcription, while the codon UAG signals the end of translation.
