Official course description: Introductory Biology 153 is a one-semester course designed for majors in Chemical and Biological Engineering and selected other engineering disciplines. The focus of the course is on exposing students to basic biological concepts and scientific thought processes. This course meets with Introductory Biology 151 and includes only the lecture (3 hours per week) and one required discussion section per week. Some engineering majors, e.g. Biomedical Engineering may be better served by taking 151 which includes a 3 hour/week lab.
