Molecular & Cellular Biology

Life at its smallest working scale: the cell and its machinery.

Content last reviewed: August 2026

Molecular and cellular biology zooms in on how cells function at the molecular level, gene expression, cell signaling, protein function, offering a more specialized and research-oriented alternative to a general biology degree. It's heavily lab-based from early in the program.

Most programs strongly encourage or require undergraduate research, working in a lab on an ongoing faculty project, since the techniques and reasoning used in the field are best learned through sustained, hands-on research experience.

Typical courses you might take

  • General Biology & Chemistry
  • Cell Biology
  • Molecular Biology
  • Genetics
  • Biochemistry
  • Developmental Biology
  • Advanced Lab Techniques
  • Undergraduate Research (multi-semester)

Sample four-year plan

Illustrative, not a registration plan

One possible way these courses could be sequenced alongside general education and elective credit. Real programs vary in order, pacing, and prerequisites by school, use this to get a rough sense of the arc, not to plan actual registration.
