The nucleus is the control center for gene expression because DNA is stored there and transcription (the process of making RNA from DNA) occurs there. The RNA then travels out of the nucleus and is translated (the process of making a protein from RNA) in the cytoplasm. The nucleolus is involved in ribosome synthesis and does not directly control gene expression. The cell membrane and Golgi apparatus are involved in other cellular processes but not in controlling gene expression.
