Question

Quizplus · Accepted Answer

Nuclear pores are large protein complexes that allow the passage of molecules in and out of the nucleus. They specifically permit the passage of proteins inward and outward, but RNA molecules only outward. Chromosomes, glucose, and assembled DNA molecules are too large to pass through the nuclear pores. Sodium ions and potassium ions are too small to be selectively controlled by the nuclear pores and are regulated by ion channels instead.
