What does the nucleus contain?

Explanation:
The nucleus houses the cell’s genetic material—the blueprint that guides every cellular function. This material is DNA, which carries the instructions for making proteins and RNAs. DNA is packaged with proteins into chromatin inside the nucleus and is organized into chromosomes during cell division. RNA is made in the nucleus from DNA, but the long-term storage of genetic information inside the nucleus is DNA. Proteins and lipids have other roles and locations in the cell, but they are not the primary content stored in the nucleus. So, the nucleus contains DNA.
