The nuclear membrane or nuclear envelope is a double-bilayer fluid-filled selectively-permeable containment that surrounds the rest of a cell's nucleus. Within the envelope is nucleoplasm in which floats the chromatin and nucleolus; these hold the cell's genetic information and instructions in the form of DNA and RNA. When a cell is ready to divide by mitosis, the membrane decomposes to permit the nucleus to divide into two nuclei; then new membranes form to enclose the two new nuclei and cell division continues until two new complete cells are formed.
It keeps the DNA all in one location. It only allows certain molecules and proteins within and without the cell. The membrane has pores that decide whether or not stuff can exit or enter the nucleus.
It controls the movement of substances such as mRNA and nucleotides in and out of the nucleus.

∙ 13y agoThe nuclear membrane is an important membrane that envelops the nucleoplasm in order to keep it separate from the cytoplasm of the cell. It's effective in maintaining the structure of the nucleus as well as regulating the in and out movements of only certain substances.

∙ 13y agoIt basically protects the nucleus like the Cell Membrane protects the cell.
Wiki User
∙ 8y agoIt surounds the nucleus and I guess you could say it kinda protects it. So that's all I know and u really !! If it doesn't I'm sorry!!!
If it doesn't help you then go Google it!!! (:

What organelle controls what enters and leaves the nucleus?
nuclear ,membrane
What are the cells of monerans do not contain?
A Nucleous
What organism lacks a true membrane bound nucleus?
Prokaryotes and Viruses
What are Cells that have organized nucleus and internal membrane structure?
Eukaryotic cells have an organized nucleus and complex internal membrane structures
What kind of cell has a nucleus surrounded by its own membrane and other internal cell parts bounded by membranes?
All cells that have a nucleus have a nuclear membrane. All nuclei are contained within a nuclear compartment which is surrounded by a membrane; sort of a balloon within another balloon.
Do archaebacteria have a cell membrane or a nucleus?
They have a cell membrane but no nucleus.
What does a nucleus membrane do?
a nucleus membrane protect any materials from it
Where is the DNA stored in a cell?
In the Membrane bound nucleus
Is the nucleus part of the nuclear membrane?
Yes. The nuclear membrane includes the nucleus. It allows movement into and out of the nucleus.
What organelle controls what enters and leaves the nucleus?
nuclear ,membrane
What sorrounds the nucleus?
Nucleus membrane
What sourronds the nucleus?
The nucleus membrane.
What is the organism that has membrane around nucleus?
Eukaryotes are the organisms that have a membrane bound nucleus.
Cell membrane is to a cell as nuclear membrane is to?
Nucleus. Cell is bound by the cell membrane, and the nucleus is bound by nuclear envelope, or nuclear membrane.
What is necleur membrane?
The nuclear membrane is the membrane that surrounds the nucleus of a cell. It is a double lipid bilayer membrane and it regulates what comes in and goes out of the nucleus.
Bacteria have a nucleus with a nuclear membrane?
No. Bacteria are prokaryotes and therefore have no membrane-bound nucleus.
What is it called if the nuclear membrane is not present in the nucleus?
If the nuclear membrane is not present in the nucleus it is called untrue nucleus, prokaryotic feature.
