That's correct! Bacterial cells are prokaryotic, meaning they lack a membrane-bound nucleus. Their genetic material (DNA) is located in a region called the nucleoid, which is not enclosed by a membrane.

Here's a breakdown:

* Eukaryotic cells (like those found in plants, animals, fungi, and protists) have a true nucleus that contains their DNA.

* Prokaryotic cells (like bacteria and archaea) do not have a nucleus. Their DNA is located in the nucleoid, a region within the cytoplasm.

This lack of a nucleus is one of the key distinguishing features between prokaryotes and eukaryotes.
