Multiple Choice

Which component houses the nucleolus and DNA within a eukaryotic cell?

The nucleus is the compartment that houses both the nucleolus and DNA. The nucleolus sits inside the nucleus and is the site where ribosomal RNA genes are transcribed and ribosome subunits begin to form. DNA is stored in the nucleus as chromatin, keeping the genetic material protected and organized. The cytosol is just the fluid part of the cytoplasm outside organelles, the Golgi apparatus mainly modifies and sorts proteins, and the endoplasmic reticulum is involved in protein and lipid synthesis but does not contain DNA or the nucleolus.
