1. What is the difference between a nucleoside and nucleotide?: A nucleosideis
formed from the covalent bonding of a base (purine or pyrimidine) to either ribose
(RNA) or 2-deoxyribose (DNA). Nucleotides are built from a nitrogen-containing
organic base, a monosaccharide, and phosphate.
2. What characteristic makes purines and pyrimidine heterocyclic?: Each hasa
ring with nitrogen in the ring instead of all carbon atoms in the ring.
3. Is this molecule ribose or 2-deoxyribose? Briefly explain what structural
