Answer for screen readers
The main component of prokaryotic DNA is located in a region called the nucleoid.
More Information
In prokaryotes, the nucleoid is an irregularly shaped region that contains the cell's genetic material. Unlike eukaryotic cells, prokaryotic cells do not have a nucleus, and their DNA is organized in a central region without a surrounding membrane.
Tips
A common mistake is confusing the nucleoid with the nucleus, as they sound similar. However, prokaryotes lack a nucleus.
