Untitled document
Upon completion of the course, student will be able to:
1.  Identify the structure and functions of major biological molecules.
2.  Describe cellular organization and structure.
3.  Explain the role and chemistry of chromosomes, DNA, and RNA in
   cell function and information transfer.
4.  Compare and contrast cellular replication/duplication by means of
   meiosis vs. mitosis.
5.  Differentiate sperm and oocyte formation, describe fertilization and
   human development.
6.  Differentiate genotype and phenotype genetic expression.
7.  Explain basic Mendelian inheritance and patterns of Mendelian
8.  Describe extensions and exceptions to Mendel's laws, including the
   inheritance of complex traits.
9.  Explain mutation and its relationship to genetic disease.
10. Describe recent advances in genetics such as recombinant DNA, genetic
   engineering, and the human genome project and how they are applied in
   gene therapy, genetic testing, and the creation of genetically-
   modified organisms.
11. Evaluate how new technologies impact us at the individual, family and
   socio-cultural levels.
12. Examine the history of eugenics and its current manifestations.

1. Reading in textbooks, scientific journals, and articles from newspaper,
  magazines and the internet; approximately 15-35 pages/week.
2. Homework: may include problem sets, and written descriptions or
  discussions of lecture topics in short essay format.
3. Oral reports: students will work in small groups, research an approved
  topic, and present a 10-15 minute report to the class.
4. Formal assessment: midterm and final examinations, including objective
  type questions, genetics problems, and essay questions.
