Biological Sciences, B.S.
The Biological Sciences major presents a unified, in-depth study of modern biology. The Biological Sciences Core is a five-quarter series of courses ranging from ecology and evolutionary biology, to genetics, biochemistry, and molecular biology. Important laboratory techniques and methodology are presented in upper-division laboratories. Advanced elective courses provide an opportunity to continue to diversify students’ exposure to the biological sciences or to gain a much more in-depth study of a particular area of the biological sciences.
NOTE: Biological Sciences majors who successfully complete their second year of study may elect to apply for a change of major to one of the following: Biochemistry and Molecular Biology, Developmental and Cell Biology, Exercise Sciences, Genetics, Human Biology, Microbiology and Immunology, or Neurobiology. Students may apply directly to the Biology/Education major or the Ecology and Evolutionary Biology major when they apply for admission to UCI. Contact the Biological Sciences Student Affairs Office for more information.
In the event that the number of students who elect Biological Sciences as a major exceeds the number of positions available, applicants may be subject to screening beyond minimum University of California admissions requirements.
Freshmen: Preference will be given to those who rank the highest using the selection criteria as stated in the Undergraduate Admissions section of this Catalogue.
Transfer students: Junior-level applicants with the highest grades overall and who satisfactorily complete course prerequisites will be given preference for admission. All applicants must complete one year of general chemistry with laboratory with grades of C or better; one year of organic chemistry with laboratory with grades of C or better; one year of biology courses equivalent to BIO SCI 93, BIO SCI 94 at UCI with a grade of C or better in each course; and have a cumulative GPA of 3.0 or higher.
No student may enter as a double major, but Biological Sciences students interested in other areas may apply to become double majors after the first quarter, if the second school or program approves. A strong academic performance in the second area is requisite for acceptance as a double major.
All students must meet the University Requirements.
All students must meet the School Requirements.
|A. Required Major Courses:|
|Select three of the following:|
|Cell, Developmental, and Molecular Biology of Plants|
|Processes in Ecology and Evolution|
|Neurobiology and Behavior|
|B. Upper-Division Laboratories:|
|Select three of the following:|
|Developmental and Cell Biology Laboratory|
|Habitats and Organisms|
|Image Analysis in Biological Research|
|Evolution and the Environment Laboratory|
|Biology of Birds Lab|
|Field Freshwater Ecology|
|Molecular Biology Laboratory|
|Experimental Microbiology Laboratory|
|Advanced Immunology Laboratory|
|Advanced Molecular Lab Techniques|
One laboratory can be satisfied with completion of Excellence in Research in the Biological Sciences.
|C. Upper-Division Biology Electives:|
|Select four upper-division, four-unit courses from the following:|
BIO SCI D103–D190, E106–E190, M114–M190, N110–N190 1
|Molecular Pharmacology I|
|Molecular Pharmacology II|
|Biopharmaceutics and Nanomedicine|
|The following course can be used to partially satisfy the Upper-Division Biology Elective Requirement:|
|Techniques in Medical Imaging I: X-ray, Nuclear, and NMR Imaging|
|Additionally, Psychology/Biological Sciences double majors may also use PSYCH 112A-PSYCH 112C to partially satisfy the Upper-Division Biology Elective Requirement.|
|NOTE: Double majors within the School of Biological Sciences or with Public Health Sciences, Biomedical Engineering: Premedical, Nursing Science, or Pharmaceutical Sciences are not permitted.|
Concentration in Biological Sciences Education
The optional concentration in Biological Sciences Education requires seven courses:
|BIO SCI 14||California Teach 1: Introduction to Science and Mathematics Teaching|
|BIO SCI 101||California Teach 2: Middle School Science and Mathematics Teaching|
|EARTHSS 1||Introduction to Earth System Science|
|EARTHSS 7||Physical Geology|
|PHYSICS 20A||Introduction to Astronomy|
|PHYSICS 20B||Cosmology: Humanity's Place in the Universe|
|Select one of the following:|
|Adolescent Development and Education|
|Multicultural Education in K-12 Schools|
|Cognition and Learning in Educational Settings|
The requirements for a general Biological Sciences B.S. degree for students in this concentration will be reduced by one upper-division laboratory course (major requirement B) and two upper-division biology electives (major requirement C). Students pursuing other majors within the School of Biological Sciences will need specific departmental approval for the reduction of degree requirements when completing this concentration.
Planning a Program of Study
Since biological sciences courses are built upon a base of the physical sciences, it is very important for students to take their required physical sciences early, particularly general and organic chemistry. Students who have not completed high school chemistry are well advised to complete a preparatory chemistry course before entering UCI. The academic program shown below is only a suggested program. Students should consult the Biological Sciences Student Affairs Office for individual academic planning.
Freshmen will normally take HUMAN 1A and HUMAN 1AS or lower-division writing courses, CHEM 1A, BIO SCI 93, and a freshman seminar (BIO SCI 2A) during the fall quarter. Students will then continue with BIO SCI 94, complete their general chemistry requirement, and continue with Humanities or lower-division writing during the remaining winter and spring quarters.
Sophomores begin organic chemistry (CHEM 51A) and continue the Biological Sciences Core with BIO SCI 97, BIO SCI 98, BIO SCI 99. Sophomores often begin taking courses in other disciplines to meet the UCI general education requirement and fulfill their mathematics requirement if they have not done so as freshmen.
During their junior year, most majors continue with the Biological Sciences electives and take physics. Students who intend to double major in Chemistry will be required to take PHYSICS 7C-PHYSICS 7D-PHYSICS 7E in place of PHYSICS 3A-PHYSICS 3B-PHYSICS 3C. Juniors may complete their general education requirements and usually start their research and their upper-division biology laboratory courses.
Finally, during their senior year, students continue their research and complete their remaining major requirements.
Students in the Biological Sciences major are required to make progress toward their degree, and their progress will be monitored. If normal academic progress toward the degree in Biological Sciences is not being met, students will be subject to probation.
