Information and Policies
Introduction
Biology has entered into an exciting new era in which phenomena that once seemed insoluble mysteries—such as embryonic development, the functions of the brain, and the dynamics of ecosystems—are now yielding their secrets as the technology to study them becomes more and more sophisticated. From molecular biology, with its potential to revolutionize medicine and agriculture, to ecology, with its lessons for the sustainable management of the environment, biologists are fully engaged in meeting the challenges of the future, helping to improve the quality of human life and to preserve habitats and biodiversity. Thus, it is no surprise that biology is at the heart of many of today’s most pressing intellectual and social concerns. The Biology B.S. degree program gives students a rigorous education in modern biology, while allowing a student the opportunity to select from a wide array of upper-division elective courses offered by the departments of Molecular, Cell, and Developmental Biology and Ecology and Evolutionary Biology. With proper advance planning, a student with virtually any degree can prepare a competitive application for medical school or health care professional school. Check the Health Careers webpage for more information on how you can academically prepare for a career in health care. Additional information is available at the UCSC Career Center.
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
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 1A, CHEM 1B, CHEM 1C, 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. Students are strongly encouraged to take STAT 5 or STAT 7 & STAT 7L and begin, if not complete, other requirements including calculus. For an overview of prerequisites and getting started in the major, please visit our biology B.S. site.
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.
Program Learning Outcomes
Students who successfully complete the Biology 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,

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 |
and all of the following courses
and one of the following courses
All qualification courses must be completed by the end of the fifth quarter.
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.
- Students with AP credit for MATH 11A or MATH 19A, BIOL 20A, BIOE 20B, and/or CHEM 1A, 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 3rd 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 decision within 15 days of the quarterly appeal deadline. See our appeal process for more information.
How to Declare a Major
Students may declare a major as early as they like, if they have decided which major to pursue and have satisfied the prerequisites or qualification requirements (if any) for the major. Students who enter UC Santa Cruz as frosh are required to be formally declared in a major before enrolling in their third year (or equivalent). Upper-division transfer students must complete the major qualification courses before entering UCSC.
Each major/minor advising office has a process for declaring. To initiate the process to declare, please complete the online declaration petition located on the Department of MCD Biology website. For assistance, please contact MCD biology advising at mcdadvising@ucsc.edu.
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 UCSC as an MCD-sponsored major. See qualifying for the major as a transfer applicant for more information.
To be considered for admission as a 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.
Plus, one of the following calculus courses:
| MATH 11A | Calculus with Applications | 5 |
| MATH 19A | Calculus for Science, Engineering, and Mathematics | 5 |
The CHEM 8A and MATH 11A or MATH 19A requirement will be enforced for transfer students entering in the fall of 2022 and thereafter. BIOL 20L is not required for students who have completed BIOL 20A and BIOE 20B from California community colleges.
In addition, the following courses are recommended prior to transfer to ensure timely graduation.
One of the following courses
| MATH 11B | Calculus with Applications | 5 |
| MATH 19B | Calculus for Science, Engineering, and Mathematics | 5 |
Plus one of the following options
Plus both of the following courses
Please see our preparing to transfer as an MCD major for more complete information.
Prospective students are encouraged to prioritize required and recommended 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 at UCSC as a Transfer Student
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.
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
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/or a faculty adviser 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.
