archea
Prokaryotes, such as bacteria and archaea, lack a true membrane-bound nucleus. Their genetic material is located in a region called the nucleoid, which is not enclosed by a nuclear membrane.
There are too types. Prokaryotes and Eukaryotes. Prokaryotic cells dont have a nucleus but have DNA. Eukaryotic cells have a nucleus enclosed by a membrane. The nucleus hold the cells DNA.
A single-celled organism without a nucleus is called a prokaryote. Examples include bacteria and archaea, which have genetic material that is not enclosed within a membrane-bound nucleus.
