Answer: ok so im so mixed up between A & C
Explanation: because Deoxyribonucleic acid (DNA) is a molecule that contains the instructions needed for an organism to develop and function. These instructions are stored as a code made up of 4 chemical bases: adenine (A), guanine (G), cytosine (C) and thymine (T). butttttt its simlier to a gene : segment of a DNA molecule (a sequence of bases) Which that'd be A ... that codes for a particular protein and determines the traits (phenotype) of the individual. A gene is the basic unit of heredity in a living organism., im pretty sure its C but it could also be A... hope this helps :/. good luck!!
