IMPORTANT NOTES – Preparation for the Major
- ★ Chem 14CL or Chem 30BL is not required on the major, but most pre-health professional schools and possibly some graduate schools still require an organic lab class.
- Students must earn a grade of C- or better in each prep course, and achieve an overall GPA of 2.0 in the prep for the major.
- Students receiving grades of below C- in two prep courses, either separate courses or repetitions of the same course, are subject to dismissal from the major.
- Students who complete Chem 20A can move to the 14 series starting with 14B, or after taking 20A, 20B, 20L may take Chem 14C, 14CL★, 14D.
- The Chemistry 14 series is unique to UCLA – there are no equivalents at other schools and must be taken in its entirety at UCLA.

Important Notes Pertaining to Major Requirements
- Any single course can be used in only ONE category on the major.
- Courses applied toward the prep and major requirements must be taken for a letter grade.
- LIFESCI 7A, 7B, 7C, 23L, and LIFESCI 107 are pre-requisites for all MCDB upper division coursework except MCDB 165A (pre-reqs: 14D or 30B and LS 7A, 7B, 7C).
- Any upper division MCDB course will be accepted as an MCDB elective, EXCLUDING MCDB 100, 104AL, 138, 144, 150AL, 165A, 187AL, 187C, 187D, 190A-C, 192A, 192B, 193, 194A, and 199.
- The MCDB department does not approve Biochemistry/MCDB or MIMG/MCDB double major petitions.
- A maximum of 4 units of approved seminar course credit may be applied to the ELECTIVES requirement (e.g., MCDB 180A, 180B, 191).
- APPLYING INDEPENDENT RESEARCH TO MCDB MAJOR REQUIREMENTS: To enroll in MCDB 196A/B, 199A-D, or 198A-D, students MUST be conducting research in an MCDB approved lab. A list of approved faculty mentors is available in the MCDB undergraduate office (128 Hershey Hall).
- APPLYING INDEPENDENT RESEARCH TO THE LAB REQUIREMENT (196A/B, 180A/B): Students must apply for these courses during their third or fourth year. Click here for more information, including application materials and instructions.
- A maximum of 12 units of research (MCDB 196A – B, MCDB 199A – C, MCDB 198A – C) may be applied to the major requirements. Please note: MCDB 196B (4 units) is applied to the upper division laboratory requirement and MCDB 196A (4 units) plus MCDB 199C (4 units) is applied toward the ELECTIVES requirement.
- If a Research Immersion laboratory and follow-up Investigations course (i.e. MCDB 104AL/104BL) is completed, 12 units of MCDB 199A-C or MCDB 198A-C may ALSO be applied to the electives. The “BL” course will be applied to the MCDB electives as well.
- Elective credit is granted for either Biostats 100A or Stats 100A, but not both.
Requirements for the B.S. degree established by the College of Letters & Science are listed in the UCLA General Catalog. A total of 180 quarter units are required for the degree; 60 of these 180 units must be upper division (course numbers 100-199). Check your DAR to determine your allotted maximum number of quarter units. NOTE: The MCDB major UD requirements satisfy 48 – 50 upper division units.
- Not all electives are offered every year. Please consult the Schedule of Classes or the appropriate department.
- When making a course plan to meet your major requirements, please make sure you have planned for all prerequisites for any upper division course in which you plan to enroll. To enroll in MCDB 168, you must have already completed MCDB 165A and MCDB 138. Courses which count on the MCDB major, may have upper division prerequisites.
- Some electives are restricted to the home department’s own majors during first pass. For example, if you want to get into MIMG 185A, you may need to wait until your second pass because you are not an MIMG major.
Computing Specialization in MCDB
Majors in Molecular, Cell, and Developmental Biology may receive a specialization in computing by:
- Satisfying all the requirements for a bachelor’s degree in the major and;
- Completing the following course requirements:
- Program in Computing 10A, 10B, and 10C
- Program in Computing 16A (Python)
- STATS 13 or Life Science 40 (Stats)
- One upper division course from:
- Computer Science CM124
- Computer Science CM186
- Chemistry & Biochemistry C100
- Chemistry & Biochemistry CM160A
- MCD BIO 187AL*
- Physiological Science 125
Students may overlap the upper division courses for the specialization with an elective or lab requirement for the major.
*Space in MCD BIO 187AL is extremely limited and computing specialization students are not guaranteed space in 187AL simply because they plan to complete the specialization.
Students must earn a letter grade of C or better in each required course for the computing specialization and a combined GPA of at least 2.o in these courses to graduate with the specialization in computing.
