Molecular biology is the study of biological macromolecules and the means by which they mediate the chemical processes of cells, regulate gene expression and define cell structure and function. This interdisciplinary major is supported by the departments of Biology and Chemistry and was made possible by a grant from the Howard Hughes Medical Institute. Students in the program have many opportunities to become familiar with and apply the approaches used in modern molecular biology research. Interest in doing research is a must for this major, since an experimental senior thesis is a requirement. During the senior year students are expected to spend at least the equivalent of two full afternoons per week working in the laboratory. A minor in Molecular Biology is not offered.
