Detailed explanation-1: -The nuclear envelope (NE) is a highly regulated membrane barrier that separates the nucleus from the cytoplasm in eukaryotic cells. It contains a large number of different proteins that have been implicated in chromatin organization and gene regulation.

Detailed explanation-2: -The nucleus is bounded by a double membrane, called the nuclear envelope. Within the double membrane nuclear envelope are passages which large molceules can pass through called nuclear pores. Each Nucleus contains one or more nucleolus; the site of ribosome synthesis.

Detailed explanation-3: -Eukaryotic cells, on the other hand, have chromosomes that are enclosed in a true nucleus, and are therefore separated from the cytoplasm by the nuclear membrane. Eukaryotic cells also have a wide range of organelles that perform specialized functions.

Detailed explanation-4: -The nuclear envelope, also known as the nuclear membrane, is made up of two lipid bilayer membranes that in eukaryotic cells surround the nucleus, which encloses the genetic material. The nuclear envelope consists of two lipid bilayer membranes: an inner nuclear membrane and an outer nuclear membrane.
