11. What are nuclear pores? State their function.

Answers (1)

Answer

Nuclear pores are the areas in the nuclear membrane where two membranes fuse. The nuclear pores allow the transfer of only some specific substances across the nuclear membrane. They allow RNA and proteins to move in and out of the membrane. These pores also transport RNA and ribosomal proteins moving from the nucleus to the cytoplasm and protein, carbohydrates, signalling molecules, and lipids moving into the nucleus. It is important that the nuclear pore complex can actively perform 1000 translocations per complex per second.
