DNA is located in the nucleus of a cell, except in prokaryotes where it is located in the cytoplasm.

Here's a breakdown:

* Eukaryotic cells (plants, animals, fungi, etc.) have a membrane-bound nucleus that houses their DNA in the form of chromosomes.

* Prokaryotic cells (bacteria and archaea) lack a nucleus and their DNA is located in a region called the nucleoid, which is a concentrated area within the cytoplasm.
