Topics:

14. Heredity and Evolution
    • Hereditary events control the passage of structural and functional information from one generation to the next
    • What are some mechanisms by which gene expression is regulated in prokaryotes and eukaryotes?
    • How do the structures of nucleic acids relate to their functions of information storage and protein synthesis?
    • What are the similarities and differences between prokaryotic and eukaryotic genomes?
    • In what ways can genetic information be altered?
    • What are some effects of these alterations?
    • What is the structure of viruses?
    • What are the major steps in viral reproduction?
    • How do viruses transfer genetic material between cells?
    • What are some current recombinant technologies?
    • What are some practical applications of nucleic acid technology?
    • What legal and ethical problems may arise from these applications?
    1. Compare and contrast the structure and functions of RNA and DNA
    2. Describe how DNA replicates itself in both eukaryotic cells and prokaryotic cells
       1. Base pairing enables existing DNA strands to serve as templates
       2. List and explain the functions of the major enzymes and other proteins that carry out DNA replications
       3. Describe how enzymes proofread and fix DNA strands
    3. Summarize experiments which helped to unwrap the DNA code
       • Griffith, Hershey and Chase, and Chargaff
    4. Go over gene regulation and mutations
    5. Describe bacterial structure and replication
    6. Describe viral structure and replication
    7. Do an overview of new nucleic acid technology and applications

Time Range:
14 days

Suggested Teaching Strategies:

• Students will read and take their own notes on the chapter (maybe in outline form)
• Science as a Process: Lecture over historical developments that led to DNA and RNA discoveries
• Review lecture on DNA and RNA structures
• Review how DNA replicates itself, making sure to discuss enzymes needed for the process
• Lecture on Viruses and bacterial DNA replications
• Students will fill out crossword puzzle that uses terms from the chapter
• Students will fill out chapter study guide to complement their lecture and board notes
• Critical Thinking: Students will use computer and do activity on 18.1 thru 21.1 on DNA Replication, Viruses and Bacteria on CD Rom from Campbell's Biology
