In a eukaryotic cell, where is DNA located?

• A. Cytoplasm
• B. Ribosome
• C. Mitochondria
• D. Nucleus

Answer: (D)

DNA in eukaryotic cells is stored in the nucleus. The nucleus is the main repository for the genome, packaged as chromatin on proteins into chromosomes, and it’s enclosed by a double membrane that regulates access to the genetic material. While small amounts of DNA exist in organelles such as mitochondria (and chloroplasts in plants), these are separate, much smaller genomes. The cytoplasm itself does not contain nuclear DNA, and ribosomes function in protein synthesis using RNA and proteins, not DNA.
