Area I Cellular/Molecular

  • BI 320 Genetics
  • BI 322 Cell Biology
  • BI 326 Immunology & Infectious Disease
  • BI 328 Developmental Biology
  • BI 360 Neurobiology
  • BI 457 Marine Biol: Mol Marine Biol (OIMB only)*

Area II Systematics/Organisms

  • BI 330/331 Microbiology and Lab
  • BI 353 Sensory Physiology
  • BI 356 Animal Physiology
  • BI 359 Plant Biology

*BI 457 Marine Biology: Marine Molecular Biology can be used to satisfy only Area I or the 400-level category.

** If BI 451 Invertebrate Zoology is used to satisfy Area II only four credits may be applied towards the 400-level credits


400-level Courses

Take 13 or more credits of 420-499 courses listed below. All of these 400-level courses are taught at OIMB during either academic or summer terms. Thirteen credits translate into a minimum of two and possibly three of the listed courses and could be done in one term at OIMB. In addition, all of these courses have field and/or lab components.

  • BI 451 Invertebrate Zoology
  • BI 458 Biological Oceanography
  • BI 457 Marine Biol: Marine Molecular Biology
  • BI 474 Marine Ecology
  • BI 455 Marine Birds and Mammals
  • BI 457 Biology of Fishes
  • BI 454 Estuarine Biology
  • BI 457 Comparative Embryology & Larval Biology
  • BI 457 Marine Conservation Biology
  • BI 457 Deep Sea Biology
  • Other topics when offered
