Ribo-This is short for ribose and it is a pentose sugar. Contrast this with the sugar group in DNA which is dexoyribose. Nucleic-Refers to the fact that it originates in the nucleus.
DNA is a double helix formed by base pairs attached to a sugar-phosphate backbone. DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms.
The structure of the double helix is somewhat like a ladder, with the base pairs forming the ladderâs rungs and the sugar and phosphate molecules forming the vertical sidepieces of the ladder. An important property of DNA is that it can replicate, or make copies of itself.
