DNA stores biological information in sequences of four bases of nucleic acid.
Explanation:
— adenine (A), thymine (T), cytosine (C) and guanine (G) — which are strung along ribbons of sugar- phosphate molecules in the shape of a double helix.
Genetic information is carried in the linear sequence of nucleotides in DNA. Each moleculeof DNA is a double helixformed from two complementarystrands of nucleotides held together by hydrogen bonds between G-C and A-T basepairs.
