Question

The nuclear membrane is often thought of as a protective structure, separating the genetic material from the rest of the cell. However, mRNA must be able to leave the nucleus to travel to a ribosome. How is this accomplished?

A. mRNA attaches to a transport protein and exits through a gated channel.
B. mRNA is small enough to diffuse across the lipid bilayer of the nuclear membrane.
C. mRNA exits through nuclear pore complexes.
D. mRNA is enclosed in vesicles which fuse with the membrane and exit.

Answer 1

C. mRNA exits through nuclear pore complexes

Step-by-step explanation:

During transcription, mRNA is produced by DNA. mRNA is transported from the nucleus to the cytoplasm, moving through the nuclear membrane through a nuclear pore. On getting to the cytoplasm, it joins with a ribosomal unit.
