Where is DNA primarily located in a typical cell?

Explanation:
DNA is primarily located in the nucleus. The nucleus houses chromosomes that contain most of the cell’s genetic material, organized and protected by the nuclear envelope to regulate gene expression and DNA replication. There is DNA elsewhere, such as in mitochondria, but that mitochondrial DNA is a small portion of the total genome. The nucleolus sits inside the nucleus as a site for ribosomal RNA synthesis and ribosome assembly, not as the main repository of the genome. The cytoplasm contains little to no DNA, so it’s not the primary location for genetic material.
