Nucleus:
- Plant and animal cells have nuclei, which is a characteristic property of eukaryotic cells.
- Plants, mammals, fungi, and protists all are eukaryotic cells.
- DNA is embedded in the nucleus, which is an organelle surrounded by a membrane called the nuclear envelope.
- Except for the cell nucleus, the cytoplasm is all of the material within a cell that is surrounded by the cell membrane.
- Chromatin is a complex of DNA and proteins that form chromosomes within the nucleus of eukaryotic cells.
- DNA does not appear in free linear strands. It is highly condensed and wrapped around nuclear proteins in order to fit inside the nucleus.
Final answer: The nucleus is present in the eukaryotic cells.
