Biomolecular and subcellular processes constitute a research area focused on the molecular mechanisms and dynamic interactions that underlie cellular function, organization, and regulation at nanometer to micrometer scales. It encompasses studies of protein folding and trafficking, nucleic acid structure and metabolism, signal transduction, membrane transport, organelle biogenesis, cytoskeletal dynamics, and macromolecular complex assembly. This field integrates biochemical, biophysical, structural, imaging, and computational approaches to quantify reaction kinetics, spatial organization, and emergent behaviors within cells, aiming to relate molecular-level events to higher-order cellular phenotypes, robustness, and dysfunction in contexts such as development, stress responses, and disease.
The enzyme RNA polymerase II transcribes genes into messenger RNA. This process is guided by modifications to the enzyme's "tail" called phosphorylation patterns.
