Detailed explanation-1: -genetic code, the sequence of nucleotides in deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) that determines the amino acid sequence of proteins. Though the linear sequence of nucleotides in DNA contains the information for protein sequences, proteins are not made directly from DNA.

Detailed explanation-2: -The actual order of the amino acids in the protein is called its primary structure and is determined by DNA. The order of deoxyribonucleotide bases in a gene determines the amino acid sequence of a particular protein.

Detailed explanation-3: -Each gene’s code uses the four nucleotide bases of DNA: adenine (A), cytosine (C), guanine (G) and thymine (T)-in various ways to spell out three-letter “codons” that specify which amino acid is needed at each position within a protein.

Detailed explanation-4: -The sequence of amino acids in a protein and protein function are determined by the genetic code. The basic building blocks of proteins. The sequence of amino acids in a protein and protein function are determined by the genetic code.

Detailed explanation-5: -Genetic code determines sequence of amino acid in protein chain. The genetic code expresses in a way that 64 Codons constitute it, as it occurs in triplets. According to the genetic code, three bases must be employed to encode the 20 standard amino acids used by living cells to build proteins.
