what does the nuclear membrane does
A nuclear membrane, also known as the nuclear envelope, is the lipid bilayer membrane which surrounds the genetic material and nucleolus in eukaryotic cells. The nuclear membrane consists of two lipid bilayersâthe inner nuclear membrane, and the outer nuclear membrane. The space between the membranes is called the perinuclear space, a region contiguous with the lumen of the endoplasmic reticulum. It is usually about 20â40 nm wide. The nuclear membrane also has many small holes called ...
