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.
Report Abuse. The structure of DNA is a double helix, much like a ladder that is twisted into a spiral shape. The nucleotide bases (A, T, C, G) that make up your genetic code are found in pairs in the middle of the helix.he base pairs that make up the rungs of the ladder are attached to the sugars in the sugar-phosphate chains that form the uprights of the ladder.
