Explanation:
Detailed explanation-1: -Like words in a sentence, the DNA sequence of a gene determines the amino acid sequence for the protein it encodes. 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.
Detailed explanation-2: -The sequence of basis on the DNA molecule is what directs the sequence of amino acids in the protein molecule-that’s how it all links together! So, the sequence of bases in DNA codes for the sequence of amino acids of a protein.
Detailed explanation-3: -The order of nitrogenous bases in DNA determines the order of amino acids in proteins.
