1014    General Biology (Zoology)
     A study of the animal kingdom from the standpoint of systematics with emphasis upon the progressive advances of tissue organization, physiology and reproductive adaptation.   Three hours lecture and three hours laboratory.  (WAC)  Fall, Spring.
 
1024    General Biology (Botany)
     A study of the plant kingdom from the standpoint of systematics with emphasis on the progressive advances of tissue organization, physiology and reproductive adaptation, including a consideration of ecological principles and economic importance of the major plant groups.  Three hours lecture and three hours lab.   Fall, Spring.
 
2014    Human Anatomy and Physiology I
     A study of the organization of the body, its tissues and the structure and functional relationships in the integumentary, skeletal, muscular, and nervous systems.  Prerequisite:  four hours biology.  Fall.
 
2024    Human Anatomy and Physiology II
     A continuation of BIOL 2104 concentrating on the cardiovascular, endocrine, respiratory, digestive, excretory and reproductive systems.  Prerequisite: four hours of Biology.  Spring.
 
3014    Microbiology
     A study of bacteria and other life forms from the standpoint of classification, morphology, physiology and environmental factors, and of the relation of bacteria to water, foods, industrial processes and diseases.  Three hours lecture and three hours lab.  Prerequisites: four hours of biology or CORE 2323; eight hours of chemistry; junior standing.  Fall.
 
3034    Ecology
     A study of the principles governing the relationships betweem plants, animals and their environment.  Consideration is given to local aquatic and terrestrial communities.  Three hours lecture and three hours lab.  Prerequisites: BIOL 1014, 1024 and four hours of chemistry.  Fall.
 
3064    Neuroscience
     An introduction to the biological substrate of behavior and experience, especially as expressed in neuroanatomy, neurophysiology and behavioral neuroscience.  Prerequisite:  CORE 2323 or BIOL 1014.  Spring of odd years.
 
3801-3894    Individual Study, Group Study, Research
    
This course is offered to provide competent students an opportunity to do independent study and research. Prior to registration, a student is required to obtain approval from a professor in the department who consents to serve as faculty supervisor. For Travel Study trips, multiple trips may be taken, but only one travel course will count toward the minimum hours for a biology major or minor. Prerequisite: Permission of supervising faculty member and department chairman.  On Demand.
 
4001    Experimental Research
     A course in lab or field research in biological science.  Course may taken only once for credit.   Prerequisite:  12 hours of chemistry, BIOL 1014, 1024 and 8 additional hours in biology. Fall, Spring.
 
4013    Histology and Microtechniques
     Lecture and lab dealing with primary tissues of vertebrate animals.  A practical course laboratory technicians, premedical students and other biology students.  Prerequisite:  BIOL 2014. Spring.
 
4042    Molecular Techniques Laboratory
     This laboratory course will cover theoretical and practical applications of molecular laboratory techniques in the context of cellular and genetic research.  It will address isolation and characterization of cellular macromolecules; standard macromolecular hybridization and identification techniques; amplification, alteration, cloning, sequencing, and expression of genetic material; basic cell culture; enzyme kinetics; common reporter assays; DNA microarrays; and other techniques applicable to modern research in genetics and cell biology.  Prerequisites:  twelve hours of biology, eight hours of chemistry.  Corequisites:  BIOL 4053 Genetics or 4063 Cell and Molecular Biology or CHEM 4023 Biochemistry or written permission of instructor and chair.  Students co-enrolled in BIOL 4053 or 4063 will receive priority placement in this lab.  Fall, Spring.
 
4053    Genetics
  
   This course is a study of the basic principles, theories and mechanisms of heredity in the context of historical Mendelian approaches and modern molecular techniques. It will address transmission genetics, population genetics, quantitative genetics and molecular genetics. The course incorporates recent research in the presentation and analytical evaluation of course material with a focus on laboratory techniques and molecular mechanisms. BIOL 4042 Molecular Techniques must be taken simultaneously unless previously completed. Prerequisites: MATH 2063, eight hours of biology, and eight hours of chemistry.  Spring.
 
4063    Cell and Molecular Biology
    
This course is designed to address general and specific principles of cellular and molecular biology.  The course covers basic chemical and physical concepts important to understanding cellular and molecular processes, cell membrane structure and function, storage and expression of genetic information, signal transduction, synthesis and function of cellular membrane systems, cellular interactions, cytoskeletal structure and function, and the cell cycle.  The course incorporates recent research in the presentation and analytical evaluation of course material with a focus on laboratory techniques and molecular mechanisms. BIOL 4042 Molecular Techniques must be taken simultaneously unless previously completed.  Prerequisites:  BIOL 1014, 2014 or 2024, 8 hours of chemistry.  Recommended:   CHEM 3005 and 3015.  Fall.
 
4801-4894    Individual Study, Group Study, Research
     This course is provided to offer competent students an opportunity to do independent study or research beyond the Experimental Research (4001) course.  Prior to registration, a student is required to obtain approval from a professor in the department who consents to serve as faculty supervisor.  On Demand.
