Information and Policies
Introduction
The molecular, cell and developmental (MCD) biology major is designed to prepare students for rigorous graduate programs in biomedical research, medical and other healthcare professional programs, for careers in the biotechnology industry. This major is more structured than the general biology major and requires that students pay careful attention to the prerequisites required for upper-division biology courses. With proper advance planning, a student with virtually any degree can prepare a competitive application for medical school or healthcare professional school. Check our Health Careers webpage for more information on how you can academically prepare for a career in healthcare. Additional information is available at the UC Santa Cruz Career Center.
Program Learning Outcomes
Students who successfully complete the MCD major will be able to:
- demonstrate knowledge of how biochemistry, genetics, and molecular biology are used to elucidate both the function of cells and their organization into tissues;
- recognize that biology has a basis in chemistry, physics, and mathematics;
- describe how scientific method is used to explain natural phenomena;
- use effective oral and written language skills to communicate scientific data and ideas;
- understand safe laboratory practices and perform basic molecular biology techniques;
- generate hypotheses, evaluate data, and design experiments to investigate a scientific problem; and
- present advanced knowledge in the specialized fields of molecular and cell biology.
Academic Advising for the Program
Students should take full advantage of academic advising and should keep in frequent contact with the advisers to stay informed about late announcements of courses, changes in scheduling, and opportunities for special study. Transfer students should also consult the Transfer Information and Policy Section. For additional advice and information:

Getting Started in the Major: Frosh
Prerequisites
Due to the demanding nature of the major, students must begin their science coursework as early as possible. MATH 11A or MATH 19A; CHEM 3A, CHEM 3B, CHEM 3C, and CHEM 8A; and BIOL 20A, BIOE 20B, and BIOL 20L must be completed before the sixth quarter in order for students to qualify for admission to MCD biology-sponsored majors, including the biology B.S., human biology B.S., molecular, cell and developmental biology B.S., and neuroscience B.S. majors. For an overview of prerequisites and getting started in the major, please visit our MCD Biology B.S. website.
An online mathematics placement examination is required to enroll in a math course. Biological science majors are expected to take this examination and are encouraged to work in the learning modules until they place into calculus. For more information see the mathematics placement website.
Transfer Information and Policy
Transfer Admission Screening Policy
MCD Biology encourages applications from transfer students in the biological sciences. The department has a major qualification policy that limits access to the program to students who have successfully completed a subset of foundational coursework. Transfer students are held to similar criteria when being assessed for admission to UC Santa Cruz as an MCD-sponsored major. See qualifying for the major as a transfer applicant for more information.
To be considered for admission as a proposed molecular, cell and developmental biology B.S. major, transfer students must complete the following courses or their equivalents prior to transfer, by the end of the spring term for students planning to enter in the fall.

Prospective students are encouraged to prioritize courses required and recommended for major preparation, and may additionally complete courses that articulate to UC Santa Cruz general education requirements as time allows.
Students who are proposed in a different major and have advanced standing when they enter UCSC require permission from the department to change into the major. Admission to the major is not guaranteed.
Getting Started in the Major: Transfer Students
Transfer students who have met the major qualification requirements are encouraged to declare the major during their first quarter at UC Santa Cruz. Transfer students should complete the required courses in genetics (BIOL 105), biochemistry (BIOL 100), and molecular biology (BIOL 101 and BIOL 101L) by the end of their first year at UCSC since they are prerequisites for the majority of other required courses.
Major Qualification Policy and Declaration Process
Major Qualification
The Department of Molecular, Cell and Developmental Biology has a qualification policy that applies to the biology B.S., molecular, cell and developmental biology B.S., and neuroscience B.S. majors.
To qualify for any of these majors, students must pass (with a grade of C or better) the following courses or their equivalents:
One of the following courses
| MATH 11A | Calculus with Applications | 5 |
| MATH 19A | Calculus for Science, Engineering, and Mathematics | 5 |
Plus one of the following options
| | Either these courses | |
| CHEM 1A | General Chemistry | 5 |
| CHEM 1B | General Chemistry | 5 |
| CHEM 1C | General Chemistry | 5 |
| | or these courses | |
| CHEM 3A | General Chemistry | 5 |
| CHEM 3B | General Chemistry | 3 |
| CHEM 3C | General Chemistry | 3 |
| | or these courses | |
| CHEM 4A | Advanced General Chemistry: Molecular Structure and Reactivity | 5 |
| CHEM 4B | Advanced General Chemistry: Molecular Structure and Reactivity | 5 |
Plus these courses
All qualification courses must be completed prior to the major declaration deadline. Students with two or more grades of NP, C-, D+, D, D-, or F in the policy courses are not qualified to declare.
When assessing qualification:
- All courses must be taken for a letter grade, see Letter Grade Policy below.
- Students with AP credit for MATH 11A or MATH 19A, BIOL 20A, BIOE 20B, and/or CHEM 3A, need only pass the remaining qualification policy courses.
- Every student who satisfies the major qualification requirements and who petitions to declare the major by the campus major declaration deadline (i.e., before enrolling in their third year or the equivalent) will be admitted to the major. Students who satisfy the major admission requirements, but who petition to declare the major after the campus major declaration deadline will be considered on a case-by-case basis for admission to the major; admission is not guaranteed.
Appeal Process
Students who are not eligible to declare the major may submit an appeal to the Molecular, Cell and Developmental Biology faculty adviser. The department will notify the student and their college of the outcome of the appeal within 15 working days of the quarterly appeal deadline. See our appeal process for more information.
How to Declare a Major
Petition to declare your major as soon as you have met qualification requirements and/or reach your declaration deadline quarter, whichever comes first.
A student's petition to declare the major will either be approved, denied, or provided with conditions (e.g., completion of some courses with certain grades) that will be resolved within at most one more enrolled quarter, even if they have not completed major qualification courses.
The Petition for Major/Minor declaration form can be accessed by going to MyUCSC and navigating to the Student Homepage and selecting the Undergraduate Student eForms tile > Petition for Major/Minor.
Letter Grade Policy
All courses that are taken to satisfy any major requirement must be taken for a letter grade.
Course Substitution Policy
At least half of the upper-division courses required for the major must be taken at UC Santa Cruz, not as transfer credits from another institution. If a student plans to transfer to UCSC from another institution, the student is advised to contact MCD Advising at UCSC before enrolling in upper-division courses at the student’s institution or any institution other than UCSC. This advising will help students understand the limitation of transferring upper-division courses from other institutions to UCSC. For more information on transferring courses to UCSC, please consult the undergraduate website.
Once matriculated, a student must receive permission from the department to satisfy the BIOL 20A, BIOL 100, BIOL 105, BIOL 101 or BIOL 110 requirements with courses taken at other institutions. Students who wish to receive credit toward the major for these or other courses taken either at UCSC or at another institution should contact MCD Advising.
Double Majors and Major/Minor Combinations Policy
Students interested in pursuing multiple majors within the biological sciences may NOT declare the following combination of majors:
- Biology (B.A., B.S., or minor) and any other biological sciences major
- Any combination of the following: human biology; molecular, cell and developmental biology; neuroscience; or biochemistry and molecular biology
Should a student choose to double major, they must qualify for and complete the disciplinary communication and comprehensive requirements for each of the majors.
Study Abroad
The UC Education Abroad Program (EAP) offers qualified students unique opportunities to broaden their educational horizons. The MCD Biology Department encourages interested students to participate. Many programs are in English-speaking countries or use English for advanced courses. Many programs offer small classes, extensive laboratories, and/or field research experience.
Students interested in study abroad need to get an early start on their basic science requirements, including chemistry, mathematics, and introductory biology and must declare their major prior to applying to go abroad. Students interested in studying abroad should visit the EAP office as soon as possible to begin planning. They should also seek advice about their EAP plan for major courses at UC Santa Cruz from MCD Advising and receive their approval.
Honors
Honors in the majors are awarded to graduating students whose academic performance demonstrates excellence at a grade point average (GPA) of 3.5 or above. Highest honors are awarded to those students whose performance demonstrates the highest level of excellence and results in a GPA of 3.8 or above.
Medical and Professional School Admission
Medical and professional school admissions requirements vary; students should verify that their coursework will satisfy the admissions requirements of the programs to which they plan to apply.
