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
