Consider the given two statements:
| Statement I: | The outer nuclear membrane usually remains continuous with the endoplasmic reticulum and also bears ribosomes on it. |
| Statement II: | Nuclear pores are the passages through which movement of RNA from nucleus to the cytoplasm and protein molecules from the cytoplasm to the nucleus takes place. |
