Definition of Nuclear envelope

A nuclear membrane, also known as the nucleolemma or karyotheca,is the phospho lipid bilayer membrane which surrounds the genetic material and nucleolus in eukaryotic cells. It should not be confused with nuclear envelope.The nuclear membrane is one of the components of the nuclear envelope. Nuclear envelope consists of the outer membrane, inner membrane, inter membrane space and associated structures. The nuclear membrane has many small holes called nuclear pores that allow material to move in and out of the nucleus.

A nuclear membrane, also known as the nucleolemma or karyotheca,is the phospho lipid bilayer membrane which surrounds the genetic material and nucleolus in eukaryotic cells. It should not be confused with nuclear envelope.The nuclear membrane is one of the components of the nuclear envelope. Nuclear envelope consists of the outer membrane, inner membrane, inter membrane space and associated structures. The nuclear membrane consists of two lipid bilayersthe inner nuclear membrane, and the outer nuclear membrane. The space between the membranes is called the perinuclear space, a region contiguous with the lumen (inside) of the endoplasmic reticulum. It is usually about 2040 nm wide. The nuclear membrane has many small holes called nuclear pores that allow material to move in and out of the nucleus.
