1Students planning to pursue the Biological Sciences, Plant Biology and Zoology programs require both Biology 313 and Biochemistry 393. Students pursuing the Biochemistry and Cellular, Molecular and Microbial Biology programs require Biochemistry 393. Students pursuing the Ecology program require Biology 313. Students in any program may take both courses should they desire. Consult specific program requirements for details.
2Check details of other programs in the Department of Biological Sciences to see where Chemistry 353 is a requirement.
3These 12 units form part of the 18 units options from outside the Faculty of Science (check Table I in 3.4 Program Requirements for ineligible courses). Of these 18 units, at least 6 units must be from the Faculty of Arts. Science 311 may be counted among the 18 units from other faculties.
