Molecular & Cellular Biology

Major Description

Molecular and Cellular Biology (MCB) is the study of living organisms through the understanding of basic molecular and cellular structure and function as well as the metabolic, genetic and physiological processes common to all organisms. Made up of the departments of biochemistry, cell and developmental biology, microbiology, and molecular and integrative physiology, the MCB major offers courses that explore unique aspects differentiating living organisms; how cells are organized; how cells and organisms respond to each other and their environment; how cells communicate signals and regulate gene expression; and how these processes go awry during injury, infection or genetic diseases. Our curriculum imparts not only basic principles of modern biology, but also the fundamental, critical and analytical skills necessary for a successful career.  

How does Molecular and Cellular Biology differ from Integrative Biology?

Those interested in conservation biology or the evolution of disease, for example, will find a good match in Integrative Biology, while those interested in the detailed workings of the human immune system or structure-function relationships in proteins will likely find more relevant courses in Molecular & Cellular Biology. Students should note which aspects of biology interest them as they take the shared introductory courses to distinguish which option will be the best fit.


Molecular & Cellular Biology is focused on the fundamental structures, functions and mechanisms of living organisms. The MCB major provides students with a solid foundation in areas that include molecular genetics, microbiology, cell biology, developmental biology, biochemistry, physiology, and structural biology.

Integrative Biology seeks to discover the complex interrelationships between organisms and the physical and biological environment in which they live. The IB major provides students with a solid foundation in areas that include anatomy, behavior, ecology, evolution, genetics, genomics and physiology.

Courses That Introduce the Major:
  • IB 150—Organismal and Evolutionary Biology
  • MCB 150—Molecular and Cellular Basis of Life

Students should consult with an academic advisor regarding course selection prior to the advanced registration period.

Possible Career Opportunities:

MCB is designed to prepare students for a wide spectrum of career opportunities: medicine, dentistry, veterinary medicine, research scientist, biotechnology and pharmaceuticals, genetic counseling, forensic science, bioinformatics and computational biology, and graduate school training.
