Problem
DNA REPLICATION:
• Explain the meaning of semiconservative DNA replication.
• Explain why DNA replication is bidirectional and includes both a leading and lagging strand.
• Explain why Okazaki fragments are formed.
Gene Transfer:
Summarize the Transformation, Transduction, and Conjugation processes under the three diagrams.
Summarize the applications of conjugation in medicine.
Bacteria Gene Expression Regulation:
• How is the synthesis of lactase enzymes (enzymes involved in breaking down the carbohydrate lactose) turned off? The answer should have the molecule's name that turns off the protein synthesis process and where it binds to stop it. Also, what is the molecule that cannot do its regular work?
• How is the synthesis of lactase enzymes turned on? The answer should include the molecule's name that inactivates the repressor and what happens when the repressor is occupied with such a molecule.
