Which are small openings in the nuclear envelope that regulate which substances enter and exit the nucleus?
nuclear pores
What is the openings in the nuclear membrane?
pores
Do a nucleus have a nuclear envelope?
The plasma membrane, which is the membrane surrounding the cell, is a single phospholipid bilayer. Embedded in it are proteins and other compounds, such as cholesterol.The nuclear envelope is double. This means that there are two phospholipid bilayers,with embedded proteins. In places the membranes connect, leaving a pore. This pore is important for permitting large molecules in and out of the nucleus, such as messenger RNA (mRNA) leaving the nucleus, and proteins synthesized in the cytoplasm entering for assembly into ribosomal subunits. Each pore is surrounded by proteins forming a nuclear pore complex.The outer membrane of the nuclear envelope is continuous with the rough endoplasmic reticulum.
What is the system of pores contained in the nuclear envelope connecting the Cell's nuclear interior with the Cell's nuclear exterior called?
These are the well defined - and just as easily assembled as they are dis-assembled - Nuclear Pore Assemblages.
What allow molecules in and out of the nuclear?
Nuclear pores allow molecules in and out
How can you describe a school using cell analogy including nuclear envelope nuclear pore vessicles cytoskeleton microfilaments microtubles centrioles rough and smooth endoplasmic reticulum?
There is no analogies for those subjects.
Do large proteins containing a nuclear localization signal bind to the nuclear pore and enter the nucleus without any expenditure of energy?
No, they do not.
What is the double membrane surrounding the nucleus?
The nuclear membrane Actually, i think it is called the nuclear envelope.
What is a nuclear pore similar to in real life?
An analogy for nuclear envelope is a gate, because the pores and RNA act like a person passing through a gate.
What a nuclear pore?
It's pretty much a pore in a nucleus.
How do matrials pass in and out of a cell nucleus?
There are small holes in the membrane of the nucleus called the nuclear pore. This allows small substances to pass into and out of the nucleus but traps large molecules like DNA and structures such as the nucleolus inside the cell nucleus.
What allows certain substances to pass into and out of the nucleus of the cell?
Nuclear membrane
