Nucleic Acids - RNA and DNA Nucleic acid is a complex, high-molecular-weight biochemical macromolecule composed of nucleotide chains that convey genetic information. The most common nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). Nucleic acids are found in all living cells and viruses.

Nucleotides Nucleotides are the building blocks of DNA and RNA. Serve as molecules to store energy and reducing power. The three major components in all nucleotides are phosphoric acid , pentose (ribose and deoxyribose), and a base (purine or purimidine). Two major purines present in nucleotides are adenine (A) and guanine (G), and three major purimidines are thymine (T), cytosine (C) and uracil (U).

Ribonucleotides Adenosine triphosphate (ATP) and guanosine triphosphate (GTP), which are the major sources of energy for cell work. - The phosphate bonds in ATP and GTP are high-energy bonds. - The formation of phosphate bonds or their hydrolysis is the primary means by which cellular energy is stored or used. nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP ). The two most common carriers of reducing power for biological oxidation-reduction reactions.
