The nucleus has a double membrane that encloses the DNA. Inside the nucleus, the DNA acts as the template to produce mRNA and ribosomes.To exit the nucleus, these molecules must
A) diffuse through the double membrane into the cytoplasm.
B) pass through carrier proteins which use ATP to transport the molecules.
C) attach to carrier molecules that carry them through the membrane.
D) pass through pores that span both membranes.
E) be transported across the two membranes by means of vesicles.

Quizplus · Accepted Answer

The nucleus is surrounded by a double membrane known as the nuclear envelope, which contains nuclear pores. These pores allow the passage of molecules such as mRNA and ribosomes from the nucleus into the cytoplasm, facilitating the flow of genetic information and protein synthesis components.
