Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Do prokaryotes have a nucleus?
A
yes
B
no
C
Either A or B
D
None of the above
Explanation: 

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

Detailed explanation-3: -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-4: -Eukaryotes are organisms whose cells contain a nucleus and other membrane-bound organelles. There is a wide range of eukaryotic organisms, including all animals, plants, fungi, and protists, as well as most algae.

Detailed explanation-5: -False. Eukaryotic cells have a nucleus and other membrane-bound organelles. In contrast, prokaryotic cells do not have a nucleus. Eukaryotic cells have a true nucleus that is surrounded by a membrane.
