COURSE CONTENT

Outcomes and Objectives:
At the conclusion of this course, the student should be able to:

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

   pedigrees.

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.

Assignments:

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.
