Question

Diameter of nuclear pore is

• A. 800 $\mathring{A}$
• B. 10 $\mathring{A}$
• C. 4000 $\mathring{A}$
• D. 2000 $\mathring{A}$

Answer 1

The correct option is A 800 $\mathring{A}$

A nuclear pore is a large protein complex that crosses the double membrane surrounding the nucleus of eukaryotic cells. These pores are aqueous channels that are generated from a complex network of evolutionarily conserved proteins known as nucleoporins. Under an electron microscope, NPC appears as a cylindrical structure measuring some 800$\mathring{A}$–1500$\mathring{A}$ nm in diameter.

So, the correct answer is option A.
