Prokaryotes are small organisms which live in a rapidly changing environment. The most important thing for them is to react in a quick and accurate way to the ever changing conditions. For example a bacterium lived in a place where Glucose was abundant, suddenly it disappeared and only lactose has left. Now it has to switch very fast to lactose usage. The best thing is to turn on all the genes related to lactose at the same time, in order to stay alive. When Glucose comes back all those genes have to be turned off at the same time to avoid waist of energy.
Eukaryotes occupy a different Ecological niche; they are more complex and more dependant of each other then Prokaryotes. They do not have to react so fast to environment- they have each other, but they have to make sure that everything is done correctly to prevent large damage to the organism. It means they need very tight supervision on everything or in other words Regulation. Individual promoters give the ability to make a much finer regulation.
Also,Unlike prokaryotes, the mRNAs of eukaryotes contain introns which have to be removed and the mRNA modified before it is been translated.

Cells are grouped into?
Prokaryotes & Eukaryotes
Did the evolution of prokaryotes preceed the evolution of eukaryotes?
Prokaryotes are a lot simpler than eukaryotes so it can be assumed that prokaryotes evolved before eukaryotes.
Which structures are common to both prokaryotes and eukaryotes?
DNA(deoxyribonucleicacid) and cell membrane
What are the differences between prokaryotes and eukaryotes?
Eukaryotes have a nucleus While prokaryotes dontProkaryotes are organisms that are made up of one cell. The most common example of this would be bacteria. Eukaryotes are organisms that are made up of multiple cells. Almost any animals you can observe normally are eukaryotes. Think of it this way: a PROkaryote is PROfessional, so they can stay alive with just one cell.
Are operons found in eukaryotes?
"False. (I found the answer in my Biology textbook)" Not true. An operon is technically more than one gene sequence that is controlled by a repressor or signal. Recent research into eukaryotic genes, especially those in protists and chordates, have revealed that eukaryotes also have operons, though they are slightly different in complexity to the ones found in prokaryotes, giving rise to the conclusion that operons are more common than expected.
Is the lac operon found in prokaryotes or eukaryotes?
The lac operon is found in enteric bacteria, predominantly Escherichia coli, therefor it is found in prokaryotes.
Cells are grouped into?
Prokaryotes & Eukaryotes
Is cytoplasm in eukaryotes or prokaryotes?
cytoplasm is found in both eukaryotes and prokaryotes.
Is choloroplast in prokaryotes or eukaryotes?
hey are only in eukaryotes. They are never in prokaryotes.
Did the evolution of prokaryotes preceed the evolution of eukaryotes?
Prokaryotes are a lot simpler than eukaryotes so it can be assumed that prokaryotes evolved before eukaryotes.
What did eukaryotes most evolve from?
Eukaryotes most likely evolved from prokaryotes.
What are the cells called that have a nucleus and organelles?
There are two basic types of cells, prokaryotes and eukaryotes. Eukaryotes differ from prokaryotes in a few ways, but the biggest difference is that eukaryotes have a nucleus and prokaryotes don't.
Are cell structures common to both prokaryotes and eukaryotes on which proteins are made?
ribosomes
Which structures are common to both prokaryotes and eukaryotes?
DNA(deoxyribonucleicacid) and cell membrane
Which has more lipids prokaryotes or eukaryotes?
eukaryotes
Are the dileptus species eukaryotes or prokaryotes?
they are eukaryotes.
Difference in prokaryotes and eukaryotes with photosynthsis?
prokaryotes have a nucleas
