Nucleoprotein is a complex in which protein is associated with the nucleic acid. These are macromolecular complexes which move to nucleus after being synthesised in cytoplasm.

Introduction:
Nucleoproteins are a type of proteins that are combined with nucleic acids, such as DNA and RNA. They play a crucial role in various cellular processes, including gene expression, DNA replication, and RNA processing. The synthesis of nucleoproteins occurs in the cytoplasm of the cell.

Explanation:
The synthesis of nucleoproteins involves the following steps:

1. Transcription:
- In the nucleus, DNA is transcribed into RNA molecules by the enzyme RNA polymerase.
- The RNA molecules are then processed to remove introns and form mature RNA.

2. Translation:
- The mature RNA molecules are transported out of the nucleus into the cytoplasm.
- In the cytoplasm, the process of translation takes place, where the RNA molecules are used as a template to synthesize proteins.
- Ribosomes, which are the cellular machinery for protein synthesis, read the RNA sequence and assemble the corresponding amino acids into a polypeptide chain.

3. Post-translation modifications:
- After the polypeptide chain is synthesized, it undergoes various post-translation modifications, such as folding, glycosylation, phosphorylation, and acetylation.
- These modifications help in the proper functioning and stability of the nucleoproteins.

Conclusion:
In conclusion, nucleoproteins are synthesized in the cytoplasm of the cell. The process involves transcription of DNA into RNA in the nucleus, transportation of mature RNA to the cytoplasm, translation of RNA into proteins by ribosomes, and post-translation modifications of the polypeptide chain. The cytoplasm provides the necessary environment and resources for the synthesis of nucleoproteins.
