Photosynthetic Processes and Mechanisms

The molecular mechanisms of biological macromolecules and their assemblies are often studied using purified material. However, the composition, conformation, and function of most macromolecules depend on their cellular context, which must be ...Cryogenic electron microscopy (cryo-EM) can reveal the molecular details of biological processes in their native, cellular environment at atomic resolution. However, few cells are sufficiently thin to permit imaging with cryo-EM. Thinning of frozen cells ...
