DNA and RNA are two types of nucleic acids that carry genetic information in living organisms. DNA, or deoxyribonucleic acid, is the primary genetic material of all living organisms and is found in the nucleus of cells. It consists of four nucleotides, which are composed of a sugar molecule, a phosphate group, and a nitrogenous base (adenine, thymine, cytosine, or guanine).
RNA, or ribonucleic acid, is another type of nucleic acid that is involved in the transmission of genetic information from DNA to protein synthesis. RNA is also composed of nucleotides.
