Bachelor of Science in Molecular Life Sciences

The Molecular Life Sciences degree within the College of Arts and Sciences fills the gap between traditional Biology and Chemistry with a modern curriculum that helps students understand the molecular basis for advances in the life sciences. Many of its faculty members are nationally or internationally known, and research-active faculty teach classes in their area of expertise. The participating faculty comprises a diverse, interdisciplinary cohort dedicated to fostering the scholarship and success of students in the program.

The Molecular Life Sciences degree is a cooperative effort between the Biology and the Molecular and Cellular Biochemistry departments. While the Life Sciences are broadly defined as the study of living organisms, we focus on understanding the molecular basis for life in complex organisms.

The best preparation for the major is rigorous course work in science and math at the high school level, especially in Chemistry and Biology. The B.S. degree in Molecular Life Sciences is designed to train students for a wide range of careers based in the life sciences. They may pursue post-graduate training in medical or dental school, in specialized degree programs such as pharmacy or pharmacology, or in graduate school in fields such as Biology and Biochemistry. Graduates may directly enter industrial settings such as the pharmaceutical industry or companies that produce biologics. Students who earn the Molecular Life Sciences B.S. degree possess a strong foundational training to enter any field dependent on the principles of life sciences.

Tracks and concentrations

The Molecular Life Sciences major offers two degree concentrations: the Molecular and Structural Biology track and the Developmental and Cellular Biology track. On one track, students study molecular aspects of cellular function and development of complex structures. On the other track, students build a molecular and structural foundation for processes such as DNA replication and repair, signal transduction, and protein metabolism. Each track develops a modern, molecular understanding of living systems from a distinct perspective.

Our Molecular and Structural Biology concentration helps you develop a contemporary, mechanistic understanding of living systems. In this concentration, you'll build a strong foundation in cell biology, molecular biology, and biochemistry. You will apply molecular and structural approaches to understand protein metabolism, learn about nucleic acid metabolism and epigenetic regulation, and explore bioinformatic approaches to characterizing biomolecules. Advanced course topics like signal transduction, which is concerned with how information flows in cells, will further your understanding of the field.

Our Developmental and Cellular Biology concentration is designed for students who are interested in exciting topics in cell biology, developmental biology, genetics, and molecular biology. You will be exposed to breakthrough advances that have been made using a variety of experimental systems including bacteria, yeast, nematodes, fruit flies, frogs, mice, and plants (just to name a few). Basic principles of cell and developmental biology that have been uncovered with these model systems are coupled with an understanding of how deviations in normal function lead to human disease. Molecular mechanisms of human disorders and diseases will be an important element of the Developmental and Cellular Biology concentration.

A Molecular Life Sciences minor is available; it is grounded in coursework drawn from either track.
