Answer: The correct answer is-
D: Prokaryotes have no nucleus.
Prokaryotes are the unicellular organisms that do not contain nucleus and membrane bound organelle in their cell. Their genetic material is present in the cytoplasm.
On the other hand, eukaryotes have true nucleus that contains the genetic material (DNA). They also contain membrane bound specialised organelles (such as mitochondria, endoplasmic reticulum, golgi complex).
The process of protein synthesis primarily involves two stages that is - 1)Transcription (DNA to mRNA, which occurs in nucleus in case of eukaryotes and in the cytoplasm in case of prokaryotes).
2) Translation (mRNA to protein) that occurs in the cytoplasm of the cell.
As prokaryotes have no nucleus, therefore, protein synthesis different in prokaryotes and eukaryotes.
