The nuclear pore complex (NPC)contains_____ structures that form a gel-like matrix that allow small molecules to diffuse through,but require larger proteins to enter via importin or other nuclear chaperones.

Question

Quizplus · Accepted Answer

The FG-nucleoporins are the structures that form a gel-like matrix within the nuclear pore complex. This matrix allows small molecules to diffuse through, but larger proteins require importin or other nuclear chaperones to facilitate their entry into the nucleus. The other answer choices (A, B, and C) are all components of the nucleus or nuclear envelope but are not directly involved in the function of the nuclear pore complex.
