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 primary structure of DNA can be broken in two parts: 1) the backbone of the molecule and 2) the bases, which are the side chains. The backbone of DNA is made up of alternating sugar (deoxyribose) and phosphate groups as seen below: sugar-phosphate-sugar-phosphate-sugar-phosphate...he primary structure of DNA can be broken in two parts: 1) the backbone of the molecule and 2) the bases, which are the side chains.
