Nuclear Envelope Formation represents a biophysical mechanism wherein the endoplasmic reticulum membranes extend to enclose the nucleus during mitosis, establishing a double-membrane boundary distinct from the cytoplasm. This process relies on the coordinated recruitment of LINC complex proteins and the nucleoporin-mediated assembly of nuclear pore complexes to ensure selective permeability and genomic compartmentalization. The concept functions as a fundamental principle within structural cell biology, defining the topological constraints and membrane dynamics required for the maintenance of eukaryotic nuclear integrity.
