Cellular and Molecular

Cellular and molecular biologists study the structure, function, and interactions of the molecules within living cells. Encompassing fields such as biochemistry, genetics, developmental biology, histology, microbiology, pathology, and physiology, this specialization underpins all biological sciences.  Cellular and molecular biology addresses questions such as: how do cells replicate themselves and grow?  How do cells acquire their specialized function?  When these processes go awry, what abnormalities or diseases result?  Focusing on cellular and molecular biology prepares students for careers in biotechnology, human medicine, regulation (whether food, drug, or environmental), veterinary medicine, and more.

Recommended Courses

Students interested in this specialization should prioritize completing genetics (BIOL 313 & lab), and molecular cell biology (BIOL 314) within the biology core curriculum. 

When planning advanced coursework, we recommend taking at least 9 credits from the list below (lab courses are denoted by • ):

Participating in experiential learning, such as an independent study course, related internship experience, and especially lab/field research is also advised.  Many students specializing in this area pursue further education with a Masters or Ph.D.

Suggested Supporting Science Courses 

Having a more comprehensive understanding of chemistry is important for specializing in cellular and molecular biology, so students should plan to take a full year of general chemistry, a full year of organic chemistry, and strongly consider taking more advanced biochemistry courses. Calculus is also used more frequently in this specialization, so students are encouraged to take at least one semester of calculus. Similarly, a full-year of physics is suggested. 

Opportunities at ISU

Biological Sciences Club (BSC)

The departmental club for Biology majors and anyone else interested in life science, the Biological Sciences Club features regular faculty speakers on a diverse range of life science topics.

Undergraduate Research Experience

Students in the Biology Program can engage in life science research and earn academic credit for the experience.  Students will learn how to seek out these opportunities during orientation and they are also welcome to discuss this with their academic advisor.  

Biochemistry, Biophysics and Molecular Biology (BBMB) Club

The BBMB Club is a departmental club that aims to foster student-faculty and student-student interactions and to help undergrads to find the next step in their career path.  

Genetics Club

The goal of the Genetics departmental club is to provide a comfortable social environment for those undergraduates interested in the field of genetics.
