Molecular, Cell, and Developmental Biology

This is an extraordinary time to be involved in biomedical research. New technologies are rapidly changing our understanding of the molecular and cellular basis of life, with dramatic implications for how we treat human disease. Members of the Department of Molecular, Cell and Developmental Biology, along with affiliated faculty in the departments of Biomolecular Engineering, Chemistry and Biochemistry, Microbiology and Environmental Toxicology, and Physics, are participating in an extraordinary revolution in biomedical science. A broad spectrum of cutting-edge research tools are being employed to tackle problems in key areas that include: the structural and functional role of RNA in regulation of gene expression; chromatin biology and epigenetic control of genes; the cell biology of the cytoskeleton and the cell cycle; decisions controlling embryogenesis and organ development; and developmental neurobiology. The insights generated by this basic research enable new strategies for treatments of aging disorders, birth defects, neurological diseases, cancer and other human ailments. The department offers a spectrum of courses that reflect the exciting new developments and directions in these fields, and trains students to participate in these exciting fields.

Students may plan a program that leads to one of several bachelor of science (B.S.) degrees. Students may choose from the following major options:

Human biology B.S.
Molecular, cell, and developmental biology B.S.
Neuroscience B.S.

Advanced undergraduates, with the guidance of faculty mentors, have access to extensive departmental laboratory facilities for independent research. Many students take advantage of the numerous opportunities with local physicians, health care providers and biotech companies to gain experience in a real world setting. This array of opportunities for directed independent study enables biological science majors to enhance their upper-division programs to reflect and strengthen their own interests and goals.

Prerequisites

Due to the demanding nature of the majors, students must begin their science coursework as early as possible. CHEM 1A, 1B and 1C, and BIOL 20A and BIOE 20B must be taken during the first and second years in order for students to qualify for admission to MCD biology-sponsored majors (see below). Students are strongly encouraged to take AMS 5 or AMS 7/L and at least one quarter of calculus during their first two years.

An online Mathematics Placement Examination is offered at various periods prior to enrollment for each quarter. Biological science majors are expected to take this examination. For more information see the Physical and Biological Sciences Undergraduate Affairs web site at http://undergrad.pbsci.ucsc.edu.

Students intending to major in human biology should take the Spanish placement examination, offered by the language program, to determine with which course they should begin the Spanish sequence.

Transfer Students

Applications from transfer students in the biological sciences are encouraged. Students who transfer without having completed the required and recommended coursework may have difficulty enrolling in courses and may require more than two years to complete a degree. Students should satisfy major qualification requirements, including required introductory chemistry and biology courses, prior to transfer. Junior-level transfer students are also strongly encouraged to complete courses equivalent to MATH 11A, MATH 11B and AMS 5 or AMS 7/L prior to transfer. Intended human biology majors are strongly encouraged to complete the Spanish language requirement prior to transfer. Prospective transfer students should review the transfer information at http://assist.org or contact the Undergraduate Affairs office for further information.

Academic Advising

Academic advising is available at the Physical and Biological Sciences Undergraduate Affairs office. Students should take full advantage of this opportunity and should keep in frequent touch with the office to stay informed about late announcements of courses, changes in scheduling, and opportunities for special study. For additional advice and information please see the undergraduate web site.

Major Requirements Qualifications Policy

The Department of Molecular Cell andDevelopmental Biology has a qualification policy that applies to the molecular, cell and developmental biology B.S.; human biology B.S. and neuroscience B.S. majors.

The UC Education Abroad Program (EAP) offers qualified students unique opportunities to broaden their educational horizons. The MCDB 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. Visit the EAP office as soon as possible to begin planning; you must seek advice about your EAP plan for major courses at UCSC from the biological sciences undergraduate adviser and/or faculty adviser and receive their approval for your plans.

Graduate Program Description

The program in molecular, cell, and developmental (MCD) biology (courses BIOL) leads to either the doctor of philosophy (Ph.D.) or the master of arts (M.A.) and is designed to prepare students for careers in research, teaching, and biotechnology. Current research in MCD biology focuses on such topics as the structure and function of RNA, gene expression, chromatin structure, epigenetics, signaling, cell division, development, nerve cell function, and stem cell biology. A unique focus of the department is the Center for the Molecular Biology of RNA.

Degree Requirements

Ph.D. and master’s students complete the graduate core courses, BIOL 200A, 200B, and 200C, and 200D in the first year. Additional undergraduate courses required to strengthen the student’s background may be assigned by the advisory committee during the initial advising meeting. Typically, these courses are Biochemistry 100A and BIOL 115. Students are required to participate in laboratory research meetings and departmental seminar series every quarter.

First-year Ph.D. students complete three 6-week laboratory rotations. Students choose their rotation laboratories in consultation with the Graduate Advisory Committee. The laboratory rotations give students a chance to learn about the diverse fields and methods of inquiry and to interact with members of the department. At the end of winter quarter, students present a short talk to the department on their rotation project. At the end of spring quarter, students consult with rotation faculty to identify a permanent thesis laboratory.

Second-year Ph.D. students are required to submit two proposals—one on their proposed thesis work and a second on an unrelated MCDB research topic. The Ph.D. qualifying examination, taken in spring quarter of the second year, is an oral examination before a committee comprised of three internal reviewers and one external reviewer.

Once the qualifying examination is passed, a student, with her/his faculty adviser, selects a thesis committee to consult with in the development of the student’s thesis. This committee monitors the student’s progress and ultimately approves the final draft of the student’s dissertation. The student must meet with the thesis committee at least once a year after passing the qualifying examination.

A student is advanced to candidacy following presentation of their research to the department in a seminar. This presentation takes place no later than spring of the third year.

Graduate students must take two approved advanced graduate electives. Students who enter the Ph.D. program with a master’s degree but without doing rotations must complete an additional two approved graduate elective courses.

Ph.D. Requirements

Complete the graduate core course

Complete the Practice of Science course

Complete an oral qualifying examination

Complete an advancement to candidacy seminar

Complete two advanced, graduate elective courses

Meet yearly with a thesis committee after the qualifying examination

Complete two quarters of service as a teaching assistant

Complete thesis research resulting in a dissertation of individual work

Present the thesis defense in a departmental seminar

M.A. Requirements

Students apply to the master’s degree program through the same portal as for the Ph.D. degree program. However, since master’s students do not do research rotations, they must identify a research adviser at the outset of the training period.

Completion of the graduate core courses

Completion of the Practice of Science course

Write a master’s thesis based on original research

Presentation of thesis defense in a departmental seminar
