Which organelle contains DNA?

Explanation:
DNA stores the cell’s genetic instructions. In eukaryotic cells, that information is housed mainly in the nucleus, where it is organized into chromosomes and kept protected. The nucleus is the central hub for genes that guide cell activities, including transcription and replication. Mitochondria do contain their own DNA, but only a small, separate genome separate from the nucleus. Ribosomes don’t contain DNA; they are made of RNA and proteins, and the Golgi apparatus has no DNA. So the organelle that contains the cell’s primary genetic material is the nucleus.
