5.50 Credits
5.5 credits. Spring Lecture and lab course emphasizing the interrelationship of vertebrate form, function, evolution, and environment. Topics include: locomotion, respiration; circulation; osmotic and ionic regulation; sensory function. The re q u i red lab includes trips to zoological gardens and the American Museum of Natural History. A discussion section is required. Prerequisite: BIO 1550 and 1560
-
5.50 Credits
5.5 credits. Alternate years (Fall) A survey of the biology of freshwater, marine, and terrestrial invertebrates. Considers stru cture, function, development, evolution, ecology, and phylogenetic relationships. The re q u i red lab includes examination of representative species and some field trips to study living invertebrates in natural environments. A discussion section is required. Prerequisite: BIO 1550 and 1560
-
4.00 Credits
4 credits. Fall Cellular organization and function, and molecular genetics, with emphasis on eukaryotic cells. Topics include: cellular genomes; replication and maintenance of genomic DNA; RNA and protein synthesis, processing, and regulation; macromolecular structure and processes of organelles; vesicular transport; cytoskeleton; the cell surface; cell signaling; and cell cycle. Students prepare a paper based on current literature in the field. A discussion section is required. Required for all biology majors immediately following BIO 1550 and 1560. Prerequisite: BIO 1550 and 1560 Prerequisite or corequisite: BIO 2890 and CHE 1550
-
3.00 Credits
3 credits. Spring A series of seminars and exercises on basic skills for research, literature review, scientific writing, and communication. Each biology faculty member presents a seminar on his or her own research, illustrating possibilities for senior projects. Students choose a senior project topic and sponsor, and prepare a formal research proposal. Required for all junior biology majors. Prerequisite: BIO 2890
-
1.00 - 3.00 Credits
and 4900 1-3 credits. Every semester Students with special interests may study independently under the sponsorship of a qualified faculty member. Independent study in general subjects is permitted if the board of study offers no formal course covering the material. Independent study in advanced or highly focused studies may be undertaken after a student has completed two 3000- or 4000-level courses in biology with a grade of B or higher. Independent study may not be substituted for a course in the “biology courses” category. A student may register fo r BIO4900 only after completing BIO 3890.
-
1.00 - 3.00 Credits
1-3 credits. Every semester Opportunities to work in research laboratories, both at Purchase and other institutions, can be arranged for a student in an area of scientific or career interest. This course may not be substituted for a course in the “biology courses” category; when appropriate, it may be usedto satisfy a lab study requirement. Prerequisite: Two 3000- or 4000-level biology courses
-
4.00 Credits
4 credits. Alternate years Lecture course examining both the humoral and cellular immune systems. Topics include: antibodies; cellular immunity; immunogenetics; inflammation and resistance to bacterial and viral infection; immunoprophylaxis, immunodiagnostics, and immunological diseases, including hypersensitivity (allergy); autoimmunity; immunodeficiency. Students prepare a paper based on current literature in the field. A discussion section is required. Prerequisite: BIO 3530; recommended but not required (one of the following): BIO 3160, BIO 3360, BIO 4620, CHE 4610
-
4.00 Credits
4 credits. Spring Stru c t u re, function, and regulation of genes at the molecular level. Topics include: transcription; RNA processing; involvement of RNA in protein synthesis; DNA replication, mutation, and repair; gene cloning; DNA sequencing; PCR amplification; applications of recombinant DNA technology (including gene therapy). Students prepare a paper on a topic in the current literature and present a seminar to the class. A discussion section is required. Prerequisite: BIO 3530 Corequisite: CHE 3320
-
6.00 Credits
6 credits. Special topic (offe red irregularly, Fall) Lecture and lab course covering the techniques of transmission electron microscopy and the principles of cell ultrastructure. Lectures consider the structural organization of the cell and its organelles. Labs include practical instruction in the basic techniques required for the preparation and examination of biological materials. A written exam, project, and report are re q u i red. Prerequisite: BIO 3530 and permission of instructor
-
4.00 Credits
4 credits. Spring P reparation and examination of biological and other materials for scanning electron microscopy. Lectures consider theoretical aspects of scanning microscopy. Labs include instruction in the techniques of tissue preparation, operation of the microscope, and darkroom procedures. Interpretation of micrographs is emphasized. A project and report are required. Prerequisite: One upper-level science course is suggested Corequisite: BIO 4665
