Definition
- Noun:
- A long linear polymer found in the nucleus of a cell: "Desoxyribonucleic acid" is a complex molecule, a polymer, that is located within the nucleus of eukaryotic cells.
- Formed from nucleotides and shaped like a double helix: It is composed of nucleotide building blocks and has a distinctive structure of two intertwined strands, known as a double helix.
- Associated with the transmission of genetic information: Its primary biological function is to store and transmit the genetic instructions used in the growth, development, functioning, and reproduction of all known living organisms and many viruses.
Usage Examples
- Noun:
