DNA can be found in the following organelles:

• Nucleus: The primary location of DNA in eukaryotic cells, housing the cell's genetic material as linear chromosomes.
• Mitochondria: Contain their own circular DNA called mitochondrial DNA (mtDNA), responsible for energy production.
• Chloroplasts: Present in plant cells, they have their own circular DNA involved in photosynthesis.

These three organelles—nucleus, mitochondria, and chloroplasts—are the main locations where DNA is found within cells.
