Question

Both prokaryotes and eukaryotes have a nucleus.

Answer 1

Actually, this statement is incorrect. Only eukaryotes have a nucleus. Prokaryotes, which include bacteria and archaea, do not have a membrane-bound nucleus. Instead, their genetic material is located in a nucleoid region, which is not enclosed by a membrane. Eukaryotes, on the other hand, have a clearly defined nucleus that houses their DNA within a nuclear membrane.
