Cytoplasmic OrganellesThe Nucleus |

|
| The nucleus contains the
cellular DNA. The inactive form of chromatin is the
heterochromatin (arrow) and the active form is the
euchromatin. In cells with a high level of activity, the
euchromatin is increased. The nucleus in this cell contains a compact nucleolus (N). Nucleoli are often large, pleomorphic and multiple in neoplastic cells. Nucleoli are rich in RNA. |
