WebThough part of the function of the nucleus is to separate the DNA from the rest of the cell, molecules must still be able to move in and out (e.g., RNA). Proteins channels known as nuclear pores form holes in the nuclear envelope. The nucleus itself is filled with liquid (called nucleoplasm) and is similar in structure and function to cytoplasm. WebCharacteristics of Eukaryotic Cells. Eukaryotic cells have the nucleus enclosed within the nuclear membrane. The cell has mitochondria.
