In prokaryotes, DNA is stored in the cytoplasm.
also prokaryotes have no nucleus
In prokaryotes, transcription and translation happen at the same time.
For one, eukaryotic DNA has sections called introns that don't code for anything. They are transcribed into mRNA, but they must be removed from mRNA before translation can occur. This is accomplished by complexes of snRNPs, or small nuclear ribonucleoproteins. The mRNA therefore has to undergo processing before it can be translated.
Prokaryotic DNA lacks introns, so mRNA can be translated *immediately* after transcription. Ribosomes often line up along a strand of mRNA to being translating it, much like beads on a string, even while the mRNA is still being transcribed. That rapid-fire change from gene to mRNA to protein could never happen in eukaryotes.
During the act of translation itself, eukaryotes use ribosomes that are slightly larger and more complex than prokaryotic ribosomes. Each type of ribosome has a sedimentation number which describes when and where it settles in a centrifuge.Eukaryotic ribosomes are 80S while prokaryotic ribosomes are only 70S.
One way that protein synthesis differs between prokaryotes and eukaryotes is that gene groups that produce proteins are organized into operons in prokaryotes, but they are not organized into operons in eukaryotes. Also, protein synthesis in eukaryotes involves more protein and is a more intricate process than in prokaryotes.
use codons to determine polypeptide sequences
Prokaryotes have no cell nucleus. Eukaryotes have a cell nucleus.
dna in eukaryotes is located in the nucleus
Eukaryotes most likely evolved from prokaryotes.

Prokaryotes have ribosomes that are necessary for protein synthesis. The ribosomes found in eukaryotes are larger compared to those found in prokaryotes.

Prokaryotes & Eukaryotes
In prokaryotes, DNA is stored in the cytoplasm. also prokaryotes have no nucleus In prokaryotes, transcription and translation happen at the same time.
Protozoans are eukaryotes. Bacteria are prokaryotes.
cytoplasm is found in both eukaryotes and prokaryotes.
hey are only in eukaryotes. They are never in prokaryotes.
Prokaryotes are a lot simpler than eukaryotes so it can be assumed that prokaryotes evolved before eukaryotes.
Eukaryotes most likely evolved from prokaryotes.
