11. These terms refer to the carbon atom in deoxyribose to which the next phosphate in the chain attaches. 12. Adenine forms adenosine, a nucleoside, when attached to ribose, and deoxyadenosine when attached to deoxyribose . 13. Thus the most likely eventuality is a deoxyribose monomer with a phosphate attached at the 5'carbon. 14. L-Deoxyribose "'is an organic compound with formula C 5 H 10 O 4. 15. It is a synthetic monosaccharide, a stereoisomer ( mirror image ) of the natural compound D-deoxyribose . 16. Every base is attached to a sugar molecule called ribose ( or deoxyribose , in the case of DNA ). 17. "' Nucleosides "'are molecules formed by attaching a nucleobase to a ribose or deoxyribose ring. 18. When guanine is attached by its N9 nitrogen to the C1 carbon of a deoxyribose ring it is known as deoxyguanosine. 19. In molecular biology, the prime is used to denote the positions of carbon on a ring of deoxyribose or ribose. 20. The nucleotides that contain a ribose sugar are the monomers of RNA and those that contain a deoxyribose sugar compose DNA.
