Nucleoplasm is the contents of the cell nucleus. It is the protoplasm inside the nuclear membrane.
- many smaller molecules, and water
- large molecules such as enzymes of many types, and nucleotides
- larger organelles such as the chromosomes and the nucleoli
- A network of nucleolar channels makes a continuous chain between the nucleoplasm and the inner parts of the nucleolus. Ribosomes made in the nucleolus get sent to the endoplasmic reticulum in the cytoplasm.
The main role of the nucleoplasm is to keep the chromosomes separate from the cell cytoplasm, and support the translating of DNA to RNA
