Courses

Freshman Level and Non-Major Courses

1301. Basic Ideas of Biology. Biological principles and information are studied by examination of a single thematic topic such as genetics. Coursework integrates the scientific discoveries within the field with applied information and societal implications. Two lectures, one laboratory period weekly. Fall and Spring.

1302. Biotechnology. The development of new methodologies in experimental biology has proceeded at an unprecedented rate in recent years, particularly in the area of DNA technology. This has enabled biologists to advance their understanding of cellular and organismal function but has also brought many practical benefits to enterprises such as agriculture and drug development. This course introduces students to some of the more important methods of biotechnology, explains their scientific basis, and describes their current applications in industry and potential for use or misuse in the future. Because the focus of the course is on DNA technology, students will be given the necessary background instruction in cell structure and function, with emphasis on the role of DNA in the life of cells. Two lectures, one laboratory period weekly. Spring.

1311, 1111. General Biology I and Lab. The first half of the general biology sequence addresses the biochemical, cellular, genetic, and evolutionary levels of biological study, providing a foundation for courses in the Molecules to Cells area of the upper-division courses in the department. Three lectures, one laboratory weekly. Fall.

1312, 1112. General Biology II and Lab. The second half of the general biology sequence addresses the diversity of life and the characteristics of the different kingdoms, as well as fundamentals of development, anatomy, physiology, and ecology of organisms.

Three lectures, one laboratory weekly. Prerequisite: Biology 1312, 1112. Spring, even-numbered years

3327, 3127. Microbiology. The majority of life on Earth, at least in terms of sheer numbers, consists of organisms too small to be seen individually with the unaided eye. All of the currently recognized domains of life are represented in the microbial world, along with the non-living viruses, viroids, and prions. This course introduces students to the structure, classification, physiology, and genetics of microorganisms, as well as their distribution in nature and interactions with humans, plants, and animals. The laboratory presents fundamental techniques for observing, handling, and cultivating microbial cells as well as methods for controlling their growth and identifying unknown microorganisms. Two lectures, one laboratory weekly. Prerequisite: Biology 1312, 1112. Fall.

3328, 3128. Molecular Biology. The structure and activity of any living organism are ultimately dependent on information stored in its DNA genome. This information must be read correctly in a time and space-dependent manner to produce the nucleic acids, proteins, and other molecules that allow cells to function. The goal of this course is to provide students with an understanding of what genes are at the molecular level, and an overview of the mechanisms involved in transmitting, maintaining, and expressing the vast reservoir of information they contain. The laboratory introduces techniques for preparing and manipulating DNA, isolating and cloning genes, and expressing foreign proteins in bacterial cells. Prerequisite: Biology 1312, 1112. Spring.

3329. Developmental Biology. Complex living organisms begin their existence as single cells, which must somehow give rise to diverse cell populations that are organized into characteristic forms and function coordinately. Developmental biology is the study of processes involved in creating a new organism and then modifying its structure in an orderly fashion as it progresses from an embryo to an adult. The goal of this course is to introduce students to fundamental anatomical, cellular, and molecular aspects of development, and to some of the rapid and exciting advances being made in this field. While we focus primarily on the animal kingdom, comparisons to other organisms are included to provide insight into the surprising conservation of genes, structures, and mechanisms that exists among living things.
