Syllabus: The Biology 12 course studies the continuity and complexity of life demonstrating the molecular basis of heredity, evolutionary change and regulation.

• Unit One: Molecular Genetics (9-10 wks)

This unit investigates the structures, functions, and replication of DNA as they relate to the continuity and complexity of living systems.

Sections:

1. Cellular Division: Mitosis and Meiosis (phases and essential structures, cancer, cloning and  chromosomal disorders). Labs may include mitosis slide viewing/sketching, karyotyping.

2. A Primer on the Chemistry of Life (biological molecules, carbon, amino acids and protein structures, nucleic acids).

3. Structure and Replication of DNA (The search for the molecule of life, the mechanisms for semiconservative replication, antiparallelism, directionality and replication bubbles). Lab may include DNA extraction, gel electrophoresis.

4. Gene Expression (Transcription, processing, and Translation, mutations, and genetic disorders).

5. Chaperones needed! Mendelian Genetics and beyond (Early ideas, Mendel, Punnett Squares and the Laws of Heredity, incomplete inheritance, polygenics and pleiotropisms, sex linkage and the chromosomal theory).

• Unit Two: Evolutionary, Change and Diversity (2-3 wks)

Diversity and variation are investigated as a reflection of the theory of evolution and its mechanism of natural selection.

Sections:

1. Pre-Darwinian ideas of Change (Malthus, Lamark, Cuvier, Lyell, etc.).

2. Darwin's Voyage on the Beagle (Darwin's evidence, this theory, and natural selection).

3. Modern Evolutionary Science (punctuated equilibrium, speciation, molecular genetics and globalization of disease, human selection).

• Unit Three: Homeostasis II (6wks)

  This unit investigates the role of chemical and electrical systems in the regulation of the body's internal environment (homeostasis).

  Sections:

  1. Overview (How the nervous and endocrine systems interact to keep us alive).

  2. Nervous System (Structure of the nervous system, stimulus/response, the reflex arc, neurons - structure and function, the action potential, transmission and the brain).

  3. Endocrine system (Structure, hormone action, negative feedback and the human reproductive system).
