Detailed explanation-1: -Prokaryotes are organisms whose cells lack a nucleus and other organelles. Prokaryotes are divided into two distinct groups: the bacteria and the archaea, which scientists believe have unique evolutionary lineages. Most prokaryotes are small, single-celled organisms that have a relatively simple structure.

Detailed explanation-2: -The most straight-forward answer would be that they do not need one. This article suggests that the evolution of the nuclear membrane allowed the separation of the processes of translation from transcription. This allowed greater control of these two key cell functions.

Detailed explanation-3: -Prokaryotic cells lack a nucleus and membrane-bound structures. Eukaryotic cells have a nucleus and membrane-bound structures called organelles.

Detailed explanation-4: -The cell membrane is bound to DNA and is in close contact with the cytoplasm. There is no enclosing membrane, because there is no actual nucleus, but merely a concentration of DNA called a nucleoid. Therefore, prokaryotes can live without a nucleus.

Detailed explanation-5: -Do prokaryotes have a nucleus? Prokaryotes do not have a nucleus. Instead prokaryote DNA can be found, bundled but free-floating, in a central region called the nucleoid. Prokaryote DNA is usually found as a single chromosome of circular DNA.
