nuclear envelope
Quick Summary
The nuclear envelope is a double membrane that encloses the nucleus in eukaryotic cells, separating it from the cytoplasm. This envelope is continuous with the endoplasmic reticulum and contains nuclear pores. These pores, regulated by protein complexes, allow for the selective transport of molecules like RNA and proteins between the nucleus and cytoplasm. This regulation is crucial for coordinated gene expression. The nuclear envelope also plays a role in organizing DNA through the nuclear lamina, a protein lining on its inner surface. During cell division, a new nuclear envelope forms around the daughter chromosomes in telophase.1234
