I: | The content of nucleolus is continuous with the rest of the nucleoplasm. |
II: | Nucleolus is the site for active ribosomal RNA synthesis. |

2. | Both I and II are correct but II does not explain I |
3. | Both I and II are correct and II correctly explains I |
4. | Only II is correct |
I: | Nuclear envelope consists of two parallel membranes with a perinuclear space between them. |
II: | Nuclear pore is formed by the fusion of two nuclear membranes at points where they interrupt the nuclear envelope. |
III: | Large and more numerous nucleoli are present in the cells actively carrying out protein synthesis. |
