The nuclear membrane is a double membrane surrounding the chromosomes of a eukaryotic cell.
Together with associated structures, it is called the nuclear envelope. Perforations in the double membrane are termed pores; each is surrounded by a group of proteins collectively called the nuclear pore complex.
The nuclear membrane defines the limit of the organelle called the nucleus. The membrane is broken into fragments during the first phase (prophase) of nuclear division. The fragments travel through the endoplasmic reticulum to the poles of the dividing cell, and are used to form the nuclear membranes of the daughter-cells.
The pores permit large molecules to enter and leave the nucleus. For example, after transcription messenger RNA passes through a pore on its way to the cytoplasm for translation. And proteins synthesized in the cytoplasm enter the nucleus via pores before being incorporated in ribosome subunits being assembled in the nucleolus. These subunits subsequently leave the nucleus through the pores.

Openings in the nuclear membrane?
Openings in the nuclear membrane are called "pores"
Do plant and animal cells have a nuclear membrane?
All plant and animal cells have nuclear membranes. The presence of a nuclear membrane distinguishes a eukaryote from a prokaryote such as bacteria.
The canals that connect the cell membrane with the nuclear membrane are?
The endoplasmic reticulum is the canal that connects the cell membrane with the nuclear membrane.
Separates nuclear contents from cytoplasm?
DNA is the nuclear content of the DNA found in nucleus. Nucleus separates the genomic DNA from cytoplasm by membrane bound organelle called nucleus. Nucleus has nucleoplasm, nucleolus and genome.
What organelle controls what enters and leaves the nucleus?
nuclear ,membrane
What is the double membrane surrounding the nucleus?
The nuclear membrane Actually, i think it is called the nuclear envelope.
Controles movement into and out of the nucleus?
nuclear membrane
What allows certain substances to pass into and out of the nucleus of the cell?
Nuclear membrane
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.
Openings in the nuclear membrane?
Openings in the nuclear membrane are called "pores"
Do plant and animal cells have a nuclear membrane?
All plant and animal cells have nuclear membranes. The presence of a nuclear membrane distinguishes a eukaryote from a prokaryote such as bacteria.
What is the function of the nuclear?
The nuclear membrane, sometimes referred to as the nuclear envelope, is the membrane that encloses the nucleus. This bilayer membrane is made of lipids, and encases the genetic material in eukaryotic cells.
The double membrane surrounding the nucleus is called what?
The nucleus of the cell is surrounded by a nuclear membrane. Like the cell membrane, this structure is also composed of phospholipids.
What does the nuclear membrane do to help a plant cell?
The nuclear membrane(nuclear envelope), surrounds the nucleus.
What is the job of an nuclear membrane?
the job of nuclear membrane is to protect the nucleus.
How is a school like a nuclear membrane?
the nuclear membrane is like the office
How doe the membrane of the cell differ from the cell nuclear membrane?
cell membrane is single whereas the nuclear membrane is double, hence it is also called nuclear envelop.
