COURSES OF STUDY
79
BI 402 Advanced Cell Biology (1)
A study of eukaryotic cells at the molecular level. Topics include protein
biosynthesis, membrane structure and function, gene expression
and regulation, cellular and subcellular structure, and the cell cycle.
Three lectures, one three-hour laboratory, and one DHAR laboratory
per week. Prerequisites: BI 125 and at least junior standing. BI 215 is
strongly recommended. Spring.
BI 405 Recombinant DNA Technology (1)
A course investigating the impact of genetic engineering in the
biological sciences. Emphasis is placed on the techniques of gene
cloning and analysis, and how these techniques are used as tools
in basic research in signal transduction, oncogenes, evolution, and
nervous system function; and in applied research in agriculture,
medicine, and industry. The social impact of recombinant DNA
technology is also discussed. Prerequisites: BI 125, 225, and 215, and
either CH 120 or 149. Spring.
BI 408 Biochemistry (1)
An introduction to the structure, chemistry, and metabolism of
carbohydrates, proteins, nucleic acids, and lipids. Three lectures, one
three-hour laboratory, and one DHAR laboratory per week. (Also listed
as CH 408, this course may be counted for credit in either biology or
chemistry.) Prerequisites: BI 125 and CH 212. Fall.
BI 410 Tropical Field Ecology (1)
A field-oriented examination of tropical ecology in Costa Rica, with
special emphasis on research methods. The course involves a six-week
stay at La Selva Biological Station in Costa Rica, where students discuss
readings, interact with researchers in tropical ecology, gain first-hand
experience exploring tropical systems, and complete a field research
project in tropical ecology. Prerequisite: consent. Occasional summers.
BI 411 General Ecology (1)
A study of organisms at the population, community, and ecosystem
levels of biological organization. Emphasis is placed on organism-
environment and organism-organism interactions. Three lectures and
one three-hour laboratory per week. Prerequisites: BI 225 and at least
junior standing. Fall of odd-numbered years.
BI 415 Evolution (1)
A study of the basic theories and processes of organic evolution with
emphasis on sources of variability and the organization of variability in
populations, population genetics, and the origin of species by natural
selection. Prerequisite: BI 215.
