What structure is outside the nucleus of a cell ad contains DNA?

Answer 1

The structure outside the nucleus of a cell that contains DNA is called the mitochondrion. Mitochondria have their own circular DNA, which is distinct from the nuclear DNA found in the cell nucleus. They are often referred to as the cell's powerhouses because they generate energy through cellular respiration. Additionally, some prokaryotic cells, such as bacteria, have DNA located in a region called the nucleoid, which is not membrane-bound like a nucleus.
