BIO 103 | Principles of Biology | 4 credit hours
The study of structure and function of living cells with special consideration of the role of membranes and enzymes in cell functioning. Emphasis is placed on the central role of DNA in directing the construction and functioning of cells. Study of the energy-transforming processes of photosynthesis and respiration and how these processes "provide" the energetic force necessary for the continued functioning of living systems - from cells to ecosystems is considered. Cell reproduction, DNA replication, chromosome separation during meiosis and the resultant predictable (and sometimes unexpected) patterns of inheritance are introduced. The relationship between genetic variation and evolution; the origin of life and the way in which subsequent evolution has given rise to the vast diversity of organisms which currently inhabit this planet are studied. Note: Either BIO 103 or 106, but not both, may be taken to fulfill the basic science requirement. Either may be followed by a second biology course. Lecture/laboratory Fall

Lecture/laboratory Prerequisites: BIO 204, 320 Fall

BIO 310 | Ecology | 4 hours
An examination of ecological principles that pertain to terrestrial populations, communities, ecosystems, biomes, and the biosphere, with a central focus on the interactions between organisms and between organisms and the non-living environment, and how such interactions manifest themselves in ecosystem patterns and processes. Laboratory and fieldwork includes student projects involving physiological ecology, vegetation sampling, study of species diversity in a variety of habitats, and analysis of prairie and forest ecosystems. Lecture/laboratory Prerequisites: BIO 103, 240 Fall

BIO 320 | Microbiology | 4 hours
The study of morphology, physiology, and systematics of bacteria with special emphasis on biochemical reactions which serve as a basis for bacterial identification. Included is a brief survey of yeasts, molds, viruses, and rickettsiae. Consideration is given to microorganisms in their relationship to disease, i.e., infection, antibiotics, and immunity; as well as their relationship to soil and water. Identification of unknown bacteria and an independent project are carried out by each student. Lecture/laboratory Minimum prerequisites: One year of chemistry and BIO 103; Recommended: BIO 203, 204 Fall

BIO 330 | Genetics | 4 hours
An introduction to the principles of classical Mendelian genetics and the principles and techniques of modern molecular genetics. Topics to be covered include Mendel's laws, gene linkage, genetic recombination and chromosome mapping, followed by a study of the chemistry of DNA and the molecular mechanics of transcription, translation, replication controls on gene expression, and modern manipulation of DNA.
