CHEM 210 Module 6 Exam Newest
1. What is the difference between a nucleoside and nucleotide?:
A nucleoside is 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 has a 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 information was used to determine this.: Ribose. This
molecule contains an -OH on carbon 2. 2-deoxyribose has an -H atom
