    Study Notes

    Meiosis

    • Understand the process of meiosis
    • Define recombinant and non-recombinant DNA
      • Determine if sexual or asexual reproduction determines recombinant and non-recombinant DNA
    • Identify the causes of genetic conditions:
      • Down's Syndrome
      • Klinefelter's Syndrome
      • Turner's Syndrome

    Genetics

    • Understand a simple Punnett square
    • Define dominant and recessive traits
    • Define genotype and phenotype
    • Understand Mendel's experiments

    Modern Understanding of Inheritance

    • Compare male and female chromosomes
    • Identify the function of genes

    Microbial Diversity

    • Understand eukaryotic organisms
      • Osmosis and diffusion
      • Examples of microbial eukaryotes (simplest example)
      • Fungi cell wall components and nutrient acquisition
    • Understand viruses
      • Components of viruses
    • Understand prokaryotes
      • DNA transfer mechanisms (e.g., conjugation)
      • Bacterial components (e.g., pili)
      • Gram-negative vs. Gram-positive bacteria

    DNA Structure and Function

    • Compare DNA and RNA (strands and nucleotides)
    • Describe the structure and function of DNA
      • Nucleotides
        • Purines and pyrimidines
        • Base pairing (which always binds with what)
    • DNA techniques (e.g., PCR)

    Adaptations

    • Understand natural selection and identify who discovered it
