7-week session | CRN 33926

The principles of molecular and cellular biology are covered in this course, with a focus on molecular mechanisms, energy and metabolism, and genetics. The emphasis is on cells as evolved systems for the capture and transformation of energy, the processing of molecular information, and the relationship between form and function. Laboratory sections scheduled throughout the series 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.
