Answer:
pores
Explanation:
The nucleus consists of "nuclear pores" on its outer membrane. Each of these are surrounded by <em>nuclear pore complex.</em> It allows the pore to <u>regulate the movement of molecules between the nucleus and the cytoplasm.</u> It allows small particles to pass through such as ribosomal proteins. It prevents most large particles<em> (except for histone)</em> from passing through; thus, <u>it is selective in nature</u>. This function of the pores clearly shows that <em>it allows communication to occur between the nucleus interior and the cytoplasm.</em>
