First year Courses with pre-registration  

Bio 115 – Molecular responses to DNA damage – TR 1-4pm: One-semester molecular biology research experience for first-year students.   Using techniques of genetics, genetic engineering, and fluorescence microscopy, students will investigate mechanisms that protect DNA, and they will study the cancer-enabling properties of cells in which critical checkpoint or repair proteins are missing.  Focusing upon a fundamental question in cancer biology – “Why do normal cells get it right every time they divide, and why do cancer cells get it wrong every time they divide?” – students will study how genome instability, marked by loss of cell cycle control and impairment of DNA repair, accelerates cancer progression.  Using the filamentous fungus Aspergillus nidulans as a model system, students will execute a genetic cross to merge an existing DNA damage mutation with a strain carrying a fluorescent marker.  Cell cycle control and DNA damage responses will then be investigated by fluorescence microscopy.  Students will perform experiments to assess qualitative and quantitative changes in nuclear morphology and kinetics of the cell division cycle conferred by defects in DNA damage responses.  This course is in addition to Bio 112 (does not substitute for Bio 112).

The application deadline has passed for Bio 115.


Bio 118 - The Chemistry of Life - and Chem 118 – The Life of Chemistry: BIO 118 and CHEM 118 are alternatives to BIO 112 and CHEM 108.  BIO / CHEM 118 will cover the same material as BIO 112 / CHEM 108, but will do so in a way that more intentionally integrates material from the two courses.  The physiological function of organ systems covered in BIO 118 will thus be taught in conjunction with the related chemistry.  For example, when we study hemoglobin in BIO 118, we'll integrate chemical considerations about the equilibrium constant for oxygen binding, and how that equilibrium is influenced by blood pH to effectively deliver oxygen to tissues and carbon dioxide to the lungs.  In lab, chemical methods will be applied to the understanding of biological processes.  All upper level courses that currently require BIO 112 and / or CHEM 108 as prerequisites (e.g., upper-level CHEM, BIO, BMB, HS, and Neuroscience courses) will also accept BIO 118 and CHEM 118.  Students who enroll in Bio 118 (MWF 10am) must also enroll in Chem 118 (MWF 11am).  Bio labs will be Mon either 1-5pm or 6:30-10:30pm while Chem labs will be at the same times on Tuesday.
