Deoxyribonucleic acid (DNA) is the biomolecule responsible for storing and transmitting genetic information in living organisms. DNA consists of two long polynucleotide chains. Each chain is composed of repeating nucleotide units, which include a phosphate group, a five-carbon sugar called deoxyribose, and one of four nitrogenous bases: adenine (A), thymine (T), guanine (G), or cytosine (C). DNA consists of two antiparallel strands held together by hydrogen bonds between complementary bases: ade
