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.

Molecular biology is concerned with understanding processes in living organisms at a molecular level, as well as the chemical and physical structure of macromolecules. Molecular biologists focus on ...

Glycobiologists often describe oligosaccharides as a third class of macromolecules, elevating them to a status otherwise reserved for nucleic acids and proteins. However, striking chemical and ...
