nuclear envelope

nuclear envelope The double membrane that separates the nucleoplasm (see nucleus) of a cell from the cytoplasm. The membranes consist of lipid bilayers that are separated by a perinuclear space (or compartment). The outer membrane is continuous with the rough endoplasmic reticulum and is structurally and functionally distinct from the inner membrane. The envelope is perforated at intervals by nuclear pores, which provide a channel for the selective transfer of water-soluble molecules between the nucleus and the cytoplasm. Each nuclear pore is surrounded by a disc-shaped structure (nuclear pore complex) consisting of an octagonal arrangement of eight protein granules.

Citation styles

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

The Chicago Manual of Style

American Psychological Association

Notes:
  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.

nuclear envelope

nuclear envelope (nuclear membrane) The structure that separates the nucleus of eukaryotic cells from the cytoplasm. It comprises 2 unit membranes each 10nm thick, separated by a perinuclear space of 10–40nm. At intervals, the 2 membranes are fused around the edges of circular pores (nuclear pores) which allow for the selective passage of materials into and out of the nucleus.
