Bacterial Diversity Studies Using the 16S rRna Gene Provide a Powerful Research-Based Curriculum for Molecular Biology Laboratory

S. Boomer, D. Lodge, and B. Dutton (Western Oregon University)


General Class Information

Molecular Biology (Bio475) is open to majors and minors in biology. Pre-requisites include one year of 200-level introductory biology and chemistry. Cell Biology (Bio388), Microbiology (Bio331), and Genetics (Bio341) are strongly recommended. Labs last 4 hours a week; students also attend 2 hours of lecture per week (total class credit = 4). The course is offered every spring and typically serves 4-8 students. The last 2 years have involved this specific project and are described.
