Explanation:
Detailed explanation-1: -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-2: -The genetic information stored in an organism’s DNA contains the instructions for all the proteins the organism will ever synthesize. In eucaryotes, DNA is contained in the cell nucleus.
Detailed explanation-3: -There are 64 different codons: 61 specify amino acids and 3 are used as stop signals.
