Hint: The nuclear envelope is composed of lipid bilayer membranes, an inner nuclear membrane, and an outer nuclear membrane. The gap between the membranes is called the perinuclear space. It is lined with a fiber complex called the nuclear lamina which is 10-40nm thick and provides strength.
Complete answer:
The nuclear envelope is also known as the nuclear membrane, is a double membrane layer that divides the contents of the nucleus from the remaining part of the cell. It is a blockade that physically protects the cell’s DNA from the chemical reactions that are occurring somewhere else in the cell. The envelope also contains a complex of proteins that keep the genetic matter in place inside the nucleus.
Additional information:
The outer nuclear membrane also shares a familiar border with the endoplasmic reticulum. The outer nuclear membrane contains proteins that are physically joined found in extremely higher concentrations than the endoplasmic reticulum.
The inner nuclear membrane encompasses the nucleoplasm and is covered by the nuclear lamina, a network of intermediate filaments that stabilizes the nuclear membrane as well as being involved in chromatin purpose and complete expression. It is linked to the outer membrane by nuclear pores that penetrate the membranes.
Note: The nuclear Envelope is typically about 20–40nm wide. The outer nuclear membrane is unremitting with the endoplasmic reticulum membrane. The nuclear envelope has numerous nuclear pores that allow materials to move amid the cytosol and the nucleus.
Intermediate filament proteins called lamina shape a structure called the nuclear lamina on the inner portion of the inner nuclear membrane and give structural support to the nucleus.
