This course examines bacterial morphology, growth, biochemistry, genetics and methods of controlling bacterial activities. Emphasis is on bacterial physiology and the role of the prokaryotes in their natural habitats. The course also covers viral life cycles and diseases caused by viruses. Prerequisites: BIO 150 and CHM 111 or equivalent advanced placement courses. Laboratory (BIO 205) must be taken concurrently.

Variable credit (2 to 10) as assigned

Techniques of modern biochemistry: ultraviolet spectrophotometry and spectrofluorimetry, SDS polyacrylamide gel electrophoresis, Scatchard analysis, and a project lab on linked enzyme kinetics. Prerequisite: BIO 203. BCH 252 is a prerequisite or must be taken concurrently.

Structure and function of biological macromolecules: proteins and nucleic acids. Mechanisms of conformational change and cooperative activity; bioenergetics, enzymes and regulation. Prerequisites: BIO 202 and CHM 223. Laboratory (253) must be taken concurrently by biochemistry majors; optional for others.

Independent research in astronomy. Admission by permission of the department. The student is expected to define her own project and to work independently, under the supervision of a faculty member.

Normally for junior and senior majors. Written project description required. A required fee of $25 to cover group-supplied materials is charged at the time of registration.

An introduction to visual experience through a study of the basic elements of drawing. A required fee of $25 to cover group-supplied materials is charged at the time of registration. Enrollment limited to 18.
