By saying nucleus, we mean that the DNA is contained in a membrane structure, that we call the nuclear membrane. However in prokaryotes (bacteria are examples!) the nucleus is not contained in a membrane structure. On the contrary, the DNA is rather suspended inside the cytoplasm itself in a compact form and is called a nucleoid.

A true nucleus is absent in bacteria and?

Instead, bacteria have a nucleoid region where the genetic material is located. This nucleoid is not surrounded by a membrane like a true nucleus found in eukaryotic cells.


Why don't bacteria have a nucleus?

Bacteria do not have a nucleus because they are prokaryotic cells, which means they lack a membrane-bound nucleus. Instead, their genetic material is found in a region called the nucleoid, which is not enclosed by a membrane. This simpler structure allows bacteria to replicate and adapt quickly to changing environments.
