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.
Nucleic Acids. The structure of DNA consists of two strands of nucleotides that are paired together to form a ladder-like structure. One strand of DNA is the template from which the other one is built. The nitrogenous bases of each nucleotide pair together in specific combinations in order to form the structure of DNA. Each rung of the ladder is a pairing of nitrogenous bases. The types of nitrogenous bases that make up RNA and DNA molecules:
