Nuclear pores are protein complexes in the nuclear envelope that regulate the transport of molecules between the nucleus and the cytoplasm. They control the movement of important substances such as RNA, ribosomal subunits, and proteins. For example, mRNA and ribosomal subunits are exported from the nucleus, while nuclear proteins are imported.

Here’s why the other options are incorrect:

B.They generate energy for the cell: This function is performed by the mitochondria, not nuclear pores. Mitochondria produce ATP,...
