Detailed explanation-1: -Each codon instructs the cell to start the creation of a protein chain, to add a specific amino acid to the growing protein chain, or to stop creation of the protein chain. For instance, a messenger RNA codon, GCA, signals the addition of the amino acid alanine to the protein chain.
Detailed explanation-2: -The genetic code includes 64 possible permutations, or combinations, of three-letter nucleotide sequences that can be made from the four nucleotides. Of the 64 codons, 61 represent amino acids, and three are stop signals.
Detailed explanation-3: -In the protein-coding region of a gene, the DNA sequence is interpreted in groups of three nucleotide bases, called codons. Each codon specifies a single amino acid in a protein. Learn about the other parts of a gene in Anatomy of a Gene.
