Bacteria are amongst the simplest of organisms – they are made of single cells. Their cell structure is simpler than the cells of animals, plants and fungi.

This is an advanced course in cell biology. In this course we will examine different areas of eukaryotic cell biology including: membrane structure and function, cell adhesion, intercellular ...

Elizabeth Kellogg, PhD, St. Jude Department of Structural Biology, used cryo-EM to study the evolutionary journey of Fanzor2, a compact eukaryotic genome-editing protein with huge potential.
