Eucaryotes evolved a nucleus from the more primative procaryotes. It was perhaps the biggest evolutionary step ever. Domains are seperated just due the presence of the nucleus. The nuclus gives the genetic material protection from the chemicals in the cytoplasm, and in turn enabled more complexity in that material and the processes it undergoes.

To whom it may concern,
Would you tell me what are the differences between Eucaryotic cell to Procariotic cell besides from that Procariotic do not build up nucleus membrane and , hope you answer me, and I would really appriciate if you do..

THANKS AND GOD SPEED 😉

To whom it may concern????

I suggest you look up the terms, not very difficult.

Yeah to whom it may concern, it means that any one who read this can you please answer me… Are you ok, aren’t you studying?? And i can use my imagination anytime. But i like to based on facts not theory, hey! please if you are not answering my question, don’t meddle to my problem. Because I even don’t know who you are, OK!!!!

We get a little testy answering questions whose answers should be easy to find with a bit of effort. If you did a simple search on eukayote prokaryote differences, you should find many places that already has the differences listed.
