BIOS S-1A Introduction to Molecular and Cellular Biology

7-week session | CRN 33926

The principles of molecular and cellular biology are covered in this course, with a focus on molecular mechanisms, energy, metabolism, and genetics. The emphasis is on cells as systems for the capture and transformation of energy, the processing of molecular information, and the relationship between form and function. Laboratory and discussion sections allow students to reinforce concepts covered in lecture. BIOS S-1a is part of an introductory biology series (BIOS S-1a and BIOS S-1b) that fulfills the medical school admission requirement of two semesters of biology. (Note: BIOS S-1a is not a prerequisite for BIOS S-1b. Students are welcome to take BIOS S-1b before BIOS S-1a.)
