While the required lecture and laboratory courses emphasize molecular and cellular biology, other required areas of study, such as genetics, evolution and developmental biology or microbiology, provide students with several elective options within these fields. Students in the Cell and Molecular Biology option also have the option of pursuing individual research for course credit. This degree requires 28 semester hours of chemistry, including a year of biochemistry and a year of physical chemistry. Thus, a student considering this option within the Biology degree needs to be competent in both mathematics and the physical sciences. A student pursuing this option is qualified, upon graduation, to attend medical or graduate schools to obtain a PhD. Alternately, the student may simply work in a research laboratory or attend law school.

Declare This Major

Current students interested in changing to the Biology major should complete the following instructions:

1. Complete the entry-level courses (Calculus 1, CH301/302, and BIO311C/D) with at least a C- or higher
2. View the online information session
3. Complete the questionnaire at the end of the session and bring it your advising appointment.
4. Schedule an appointment with the Biology Advising Center.

Current students who have not yet completed the entry-level requirements should schedule an appointment with an academic advisor in WCH 1.106. Contact the appropriate College of Natural Sciences Advising Center to schedule an appointment and change majors to Biological Sciences entry-level.

Prospective University of Texas at Austin students should visit to learn about the application process and how to declare a major.
