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 Chemical Structure of DNA. DNA is a linear polymer, which means it is a chain of units, or monomers. The monomers of DNA are called nucleotides. Each nucleotide contains a phosphate, a sugar, and a base.There are four nucleotide types, identical except for the base.he Chemical Structure of DNA.
