Biology

Overview

What do Ebola, hemophilia, DNA fingerprinting, sequoias, cuttlefish, intertidal zones, and global climate change have in common? These are a few examples of the diverse topics that are explored in biology, which is the scientific study of living organisms, including their structure, function, evolution, and interactions with other organisms and the environment. The CRC Biology Department offers a variety of courses that are organized into the following three areas:

  • Clinically related courses for students pursuing careers in nursing and allied health (BIOL 100, 102, 302, 430, 431, 439, and 440)
  • The first two years of a Biology major for those transferring to Bachelor's Degree programs in fields related to the life sciences (BIOL 400, 410, and 420)
  • General education courses for non-science majors who want to gain an understanding of the biological world (BIOL C1001, C1001L, 342, 350, 352, 390, and 485)

Students who transfer to four-year universities report high satisfaction with the education they received at CRC.

Degrees Offered

  • A.S.-T. in Biology
  • A.S. in Biology
  • A.S. in Biology: Pre-Nursing Option
  • A.S. in General Science

Associate Degrees for Transfer

A.S.-T. in Biology

The Associate in Science in Biology for Transfer Degree is designed to prepare students for a seamless transfer into the CSUsystem to complete a baccalaureate degree in Biology or a similar major. Students with this degree will receive priority admission with junior status to the California State University system. The Associate in Science in Biology for Transfer is comprised of lower division coursework typically required by CSU institutions. Students must complete the following Associate Degree for Transfer requirements (Pursuant to SB1440, §66746):

• Completion of 60 semester units or 90 quarter units that are eligible for transfer to the California State University.
• The California General Education Transfer Curriculum (Cal-GETC) pattern.
• A minimum of 18 semester units or 27 quarter units in a major or area of emphasis, as determined by the community college district.
• Obtainment of a minimum grade point average of 2.0.
• A grade of “C” (or “P”) or better in all courses required for the major.

Completion of the AS-T degree may not prepare students to transfer to University of California biology programs that may have different requirements. If a student intends to transfer to University of California, additional courses in chemistry, physics, and math may be required.

Note to Transfer Students:
The Associate Degree for Transfer program is designed for students who plan to transfer to a campus of the California State University (CSU). Other than the required core, the courses you choose to complete this degree will depend to some extent on the selected CSU for transfer. In addition, some Cal-GETC requirements can also be completed using courses required for this associate degree for transfer major (known as “double-counting”). Meeting with a counselor to determine the most appropriate course choices will facilitate efficient completion of a student’s transfer requirements. For students wishing to transfer to other universities (UC System, private, or out-of-state), the Associate Degree for Transfer may not provide adequate preparation for upper-division transfer admissions, because many universities require more lower division courses than those in this degree. Even the CSU's that accept this transfer degree may likely require additional lower division courses to achieve the Bachelor degree. It is critical that students meet with a CRC counselor to select and plan the courses for the major, as programs vary widely in terms of the required preparation.
