Introductory Genetic Analysis, commonly referred to as just plain
Genetics, is the sister course to Cell
Physiology; most students who take Genetics first semester take
Cellphys second semester. Genetics introduces students to Mendelian,
molecular, and medical genetics, in both a historical and present
day context. Specific topics include, but are not limited to: Genetics'
History, Monohybrid and Dihybrid Crosses, Hardey-Weinberg Equilibrium,
Meiosis and Mitosis, Karyotypes, Chromosome Aberrations, DNA Replication,
Transcription, and Translation, Genetic Testing, Manipulation of DNA,
Gene Regulation, Bacterial/Phage Genetics, Mutation, Gene Therapy,
the Human Genome Project, Cancer, AIDS, Bioethics, and Homeotics (Whew!).
Hands on laboratory exercises, problem solving sessions, student-led
seminars, field trips, and other class activities compliment the lectures
and discussions in the class. By the end of the course, students will:
- Be able to draw upon the historical significance and classical
laws of genetics.
- Become familiar with recombinant DNA technology through laboratory
exercises on the molecular level.
- Be able to relate generalized ideas in genetics to specific molecular
events.
- Be able to relate chromosome structure to function.
- Read and report on original research found in scientific journals.
- Debate the ethical issues surrounding current genetic research.
As mentioned above, there are a number of labs performed during the
course of the class. While these can vary from year to year, a typical
set includes:
- Preparation of Human Chromosome Spreads Students observe
chromosomes from a human tumor cell line.
- Isolation of DNA from an Onion Students use chemical and
mechanical means to isolate DNA.
- Human Inheritance Lab Students investigate the Hardey-Weinberg
principle.
- Measurements, Micropipetting, and Sterile Technique Students
learn how to work with small volumes with micropipets.
- Genetics and Sickle Cell Anemia Students use protein electrophoresis
to compare normal and sickle cell hemoglobin.
- Bacterial Cultural Techniques: Isolation of Individual Colonies
Students learn how to culture bacteria on solid media.
- Bacterial Cultural Techniques: Overnight Suspension Culture
Students learn how to culture bacteria in liquid culture.
- DNA Restriction Analysis Students use enzymes to cut phage
DNA and compare electrophoretic patterns of different digests.
- Principle of Polymerase Chain Reaction Students analyze
PCR products through gel electrophoresis.
- Rapid Colony Transformation of E.Coli with Plasmid DNA
Students use chemicals and heat shock technique to transform ampicillin
sensitive bacteria into ampicillin resistant bacteria.
- Purification and Identification of Plasmid DNA: Plasmid Miniprep
of pAMP Students isolate the transforming plasmid from the
bacteria from the Rapid Colony Transformation lab.
- Purification and Identification of Plasmid DNA: Restriction Analysis
of purified pAMP Students digest their miniprep plasmid DNA
and compare its electrophoretic pattern with control plasmid DNA.
