Deoxyguanosine
Deoxyguanosine
Deoxyguanosine (pronounced dee-ox-ee-gwah-no-seen) is a nucleoside that is composed of guanine and deoxyribose. It is a component of DNA and plays a crucial role in the genetic code.
Etymology
The term "Deoxyguanosine" is derived from the words "deoxyribose" and "guanine". "Deoxyribose" is a sugar derived from ribose by replacement of a hydroxyl group by hydrogen, while "guanine" is one of the four main nucleobases found in the nucleic acids DNA and RNA.

- Guanine: Guanine is one of the four main nucleobases found in the nucleic acids DNA and RNA.
- Deoxyribose: Deoxyribose is the sugar component in the backbone of DNA, differing from ribose by having a hydrogen atom instead of a hydroxyl group at the 2' position.
- DNA: DNA, or deoxyribonucleic acid, is a molecule composed of two chains that coil around each other to form a double helix carrying genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses.
