300-Level Course Descriptions
To enroll in 300- or 400-level Biology courses, students must have achieved a grade of "C" or better in BIOL 104, BIOL 106 and CHEM 161, CHEM 162.
BIOL 301 Evolutionary Biology (3)
This course explores the principles of evolutionary biology through a discussion/lecture format. Topics covered include the theory of evolution, origin of new species, genetics of populations, relative roles of selection, drift, mutation, and migration in the evolutionary process, evolutionary rates, and pre-biotic evolution.
BIOL 302 Cellular Biochemistry & Molecular Biology (3)
This fall course covers cellular organization and function at the molecular level; the structural building blocks of the cells (lipids, nucleic acids, amino acids, and carbohydrates) and their functional integration into macromolecules and organelle compartments. Also covered is DNA replication, RNA structure and function, and transcriptional and translational controls of protein biosynthesis. Co-requisite: CHEM 342, 344.
BIOL 303 Principles of Genetics (3)
This course covers the basic concepts of the transmission and function of genes at the molecular, organismal, and population levels. Recombinant DNA technology and its utility in research and industry will also be covered. Prerequisite: CHEM 342, 343 or concurrent enrollment, and BIOL 302.
BIOL 304 Cellular Structure & Function (3)
Detailed topics of this spring course include membrane structure/function, mitochondrial and chloroplast energy transduction and cellular thermodynamics, nuclear-cytoplasm information flow, protein sorting and modification in the ER and Golgi, the cytoskeletal framework, cell-cell signaling, cell cycle control, and the extracellular matrix and cell adhesion. Prerequisite: BIOL 302.
BIOL 306 Cell Structure & Function Laboratory (2)
Laboratory four hours per week. Basic concepts in cell biology stressed in a laboratory setting (spring semester). Protein and lipid components of biological membranes, DNA comparison of prokaryotic and eukaryotic organisms, principles of protein synthesis, establishment of primary cell cultures, analysis of the cytoskeleton and the extracellular matrix. Techniques stressed will include microscopy (light/fluorescent), SDS-PAGE and protein determination, thin layer chromatography, receptor analysis and the application of sterile culture to the study of cells. Prerequisite: BIOL 304 or concurrent enrollment .
BIOL 310 Experiments in Genetics (2)
Laboratory four hours per week. Advanced experiments in classical and molecular genetics will be conducted by the students. Data will be collected, analyzed, and reported. Prerequisite: prior completion of BIOL 303 or its equivalent.
BIOL 312 Experimental Cell Biology (5)
Lecture three hours, laboratory five hours per week. This SLU2000 course in the sophomore biology major series is designed to integrate lab and lecture experiences as they are applied to the study of cell biology. Research approaches that stress how core information in cell biology has been obtained and how novel techniques continue to enrich this discipline will be explored. This is a laboratory intensive course that will substitute for the required second semester BIOL 304 and 306 courses for biology majors. Prerequisites: BIOL 302 with a grade of 'B' or better and a recommendation from a student's advisor.
BIOL 322 Biology of Invertebrates (4)
Lecture three hours, laboratory three hours per week. This course surveys the invertebrate phyla with emphases on evolution, comparative morphology, life cycles, physiology, and ecology.
BIOL 326 Biology of Plants and Fungi (4)
Lecture three hours, laboratory four hours per week. An introduction to algae, fungi, and true plants comparing life cycles (alternation of generations) and functional anatomy/morphology. Half of the course emphasizes the four developmental stages in the life of seed plants: germination, establishment, maturation, and reproduction.
BIOL 328 Ethnobotany (3)
A modern synthesis of plant biology and the principles of cultural anthropology to compare the use of domesticated and wild plants. A comparison of tropical and temperate zone 'cases' requires four field trips to the Missouri Botanical Garden. Satisfies the Arts and Sciences Cultural Diversity requirement.
BIOL 340 General Ecology (4)
Lecture three hours, laboratory three hours per week. An introduction to the science of ecology: study of general theories, models, and problems in population, community, and ecosystem levels.
BIOL 342 Comparative Anatomy (4)
Lecture two hours, two three-hour laboratories per week. Evolution of chordate morphology. Laboratory consists of the study of the structures of each major group of chordates with emphases on the dogfish shark and cat.
BIOL 344 Embryology (5)
Lecture three hours, and two two-hour laboratories per week. Development of the vertebrate embryo from a single cell into a multicellular organism. Topics include: fertilization, changes in shape and form, increase in complexity and diversity, organ formation, processes by which cells with the same genetic endowment become different from one another. Prerequisite: Sophomore standing.
BIOL 346 General Physiology (3)
Cellular and molecular mechanisms underlying the regulation and function of human organ system physiology. Topics include: membrane biology; endocrinology; signal transduction; neurophysiology and nervous systems; smooth and striated muscle; cardiovascular, pulmonary, and renal physiology; and fluid and electrolyte homeostasis. Prerequisites: BIOL 302 and 304, or BIOL 261 for BME students.
BIOL 347 General Physiology Laboratory (2)
Laboratory three hours per week. This laboratory course is designed to supplement and reinforce material presented in the BIOL 346; largely through computer-based interactive physiology programs, and the acquisition and analysis of cardiovascular, neuromuscular, and respiratory systems data using the PowerLab human physiology teaching system. Problems involving inquiry-based learning are also assigned. Pre- or co-requisite: BIOL 346.
BIOL 349 Plant Physiology (3)
Principles of plant physiology: growth, phytohormones, flowering, photosynthesis, water relations, mineral nutrition, translocation in higher plants.
BIOL 350 Biodiversity of Africa I (0)
Lecture three hours per week. An introduction to the biodiversity of the tropical rainforest of equatorial Africa and the role this biodiversity plays in the culture of the native peoples of Gabon and Cameroon. This course is a prerequisite for BIOL 351.
BIOL 351 Biodiversity of Africa II: Field Trip (3)
A field trip to study the biodiversity of the tropical rainforest and the role this biodiversity plays in the culture of the native peoples of Gabon and Cameroon. Satisfies the Arts and Sciences Cultural Diversity requirement.
