Nucleic acids are macromolecules, which means they are molecules composed of many smaller molecular units. Thes units are called nucleotides, and they are chemically linked to one another in a chain.

Macromolecules - proteins, nucleic acids, and polysaccharides - are formed by the polymerization of hundreds of their low-molecular-weight precursors - amino acids, nucleotides, and simple sugars.

In the case of nucleic acid tests, polymerase chain reaction (PCR) has been the gold standard for single-molecule diagnosis. Single-molecule detection of pathogens, such as severe acute ...

Biomolecules—molecules produced by a living organism, such as proteins—are surrounded by thousands of water molecules, along with other proteins, nucleic acids and other types of molecules.
