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.
A closer look at the chemical structure of DNA includes the four nitrogenous bases Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). DNA also includes sugars and phosphate groups that make the phosphate-deoxyribose backbone.If you think of the structure of DNA as a twisted ladder, the rungs of the ladder are made from the nitrogenous bases. These bases pair up to make each step of the ladder. They also only pair up in a specific way.NA also includes sugars and phosphate groups that make the phosphate-deoxyribose backbone.
