3. List the three components of a nucleotide.
4. Distinguish between deoxyribose and ribose.
5. List the nitrogen bases found in DNA, and distinguish between pyrimidine and purine.
6. Explain how Watson and Crick deduced the structure of DNA, and describe what evidence they used.
7. Explain the "base-pairing rule" and describe its significance.
8. Describe the structure of DNA, and explain what kind of chemical bond connects the nucleotides of each strand and what type of bond holds the two strands together.
9. Explain, in their own words, semiconservative replication, and describe the Meselson-Stahl experiment.
10. Describe the process of DNA replication, and explain the role of helicase, single strand binding protein, DNA polymerase, ligase, and primase.
11. Explain what energy source drives endergonic synthesis of DNA.
12. Define antiparallel, and explain why continuous synthesis of both DNA strands is not possible.
13. Distinguish between the leading strand and the lagging strand.
14. Explain how the lagging strand is synthesized when DNA polymerase can add nucleotides only to the 3' end.
15. Explain the role of DNA polymerase, ligase, and repair enzymes in DNA proofreading and repair.
