  • BIOL 230: Biology of Cells And Genes

    3.00 Credits
    Widener University-Main Campus

    This course is an exploration of the inner workings of eukaryotic cells. Students focus on structure-function relationships while examining organelles, cell physiology, intracellular communication, and the flow of information from DNA to protein (replication, transcription, and translation). Principles of classical genetics, molecular genetics, and the regulation of gene expression are considered. The laboratory emphasizes diagnostic and forensic applications of modern cell biological and genetic analysis. This course is intended for nonscience majors and is not open to biology majors. Premedical students (regardless of major) should enroll in BIOL 261. Prerequisites: BIOL 121, 122, and CHEM 101, 102. 3 hours lecture. 3 hours laboratory. 4 semester hours

  • BIOL 261: Biological Concepts III- Principles of Cellular And Molecular Biology

    4.00 Credits
    Widener University-Main Campus

    This course is intended for biology majors and premedical students. The course, the third in the core curriculum, focuses on cellular and intracellular processes amongst all living organisms. Students examine cell physiology of both prokaryotes and eukaryotes. Topics include energy metabolism, such as fermentation, respiration and photosynthesis, and the core metabolic pathways, such as the biosyntheses of amino acids and nucleotide precursors. Special attention is paid to the flow of information from DNAto protein (replication, transcription and translation) and the regulation of gene expression. The course also connects the ecological and physiological phenomena studied in the first two courses of the core to the fundamental intracellular processes that determine organismal performance. Prerequisite: BIOL 161, 162, and CHEM 102 or 146 or permission of instructor. 3 hours lecture. 3 hours laboratory. 1 hour discussion. 4 semester hours

  • BIOL 262: Principles Ofmodern Genetic Analysis

    4.00 Credits
    Widener University-Main Campus

    This course focuses on the important concepts of classical, molecular, and population genetics. Discussion of Mendelian genetics is integrated with coverage of the relevant topics in cellular and molecular genetics. The course places special emphasis on problem solving skills and genetic analysis. Topics include the structure of genes and genomes across the wide range of living organisms; mechanisms of inheritance and recombination; gene expression and mutation; chromosome structure and the role of chromosomal changes in evolution; recombinant DNA technology and its application to modern biology; and population genetics and mechanisms of evolution. The laboratory includes experimentation with live organisms, including transmission genetics in the fruit fly, Drosophila melanogaster, and genetic recombination in the bacterium, Escherichia coli. Exercises also include computer modeling of genetic systems and analysis of computer generated data. Each student clones and characterizes a restriction endonuclease fragment of the bacteriophage Lambda genome in an E. coli host/plasmid vector system during a seven-week-long laboratory project. This project lab incorporates many of the basic tools of recombinant DNA technology. Prerequisite: BIOL 261 and CHEM 255. 4 semester hours

  • BIOL 301: Introductory Ecology

    4.00 Credits
    Widener University-Main Campus

    This course teaches ecological and environmental literacy. Participants will understand (1) the physical, biological, and evolutionary processes that determine ecosystem structure and function, and (2) the process of ecological inquiry that is the scientific method, through which natural phenomena are observed, interpreted, and reported. This course teaches students how to read global environmental signposts (climate changes, ozone depletion, and biodiversity loss), recognize their role in causing these trends, and evaluate the courses of action, in terms of consumer and disposer decisions, they must take in order to sustain themselves. Prerequisite: BIOL 262 or its equivalent, or permission of the instructor. 3 hours of lecture. 3 hours lab and field work. 4 semester hours
