What is the job of a nuclear pore?

Answer 1

Nuclear pores are on the membrane of the nucleus of a cell, and they allow the trasport of water-soluable materials through the membrane. There are roughly 2000 pores on one nucleus, and they are each about 120 nm (nano-meters) across.

Answer 2

If I understand the question and the category correctly, you are asking about nuclear pore which is a hole in the nuclear envelope.

To elaborate a little, the information for running the business of any particular cell is contained in the nucleus of the cell. It is like locking the secret formula up in a safe or vault. When the nucleus gets a message that it needs to produce a certain protein, a complex series of events take place which unlock that gene for that protein. The double helix of DNA opens up just at the place where the formula for that protein resides.

Single-stranded RNA, called messenger RNA or mRNA, takes an encrypted message off the DNA which contains the formula for the protein. This mRNA then travels out of the nucleus through a nuclear pore. After exiting the nucleus, the mRNA attaches to a ribosome where the protein is assembled. After delivering its message, the mRNA is broken up so the message cannot be used again without creating a new mRNA in the nucleus.

Answer 3

The nuclear pores, serve as the pathways for the exchange of the materials between the nucleus and the cytoplasm.

Answer 4

A nuclear pore allows the passage of certain molecules through the nuclear envelope while blocking other molecules.

Answer 5

To send proteins and other molecules in and out of the cell

Answer 6

Nuclear pores allow molecules to move through the nuclear envelope.
