which of the following regions of the cell can protein synthesis occur in eukaryotes?
Besides the absence of nucleus in prokaryotes, the lower level of cell compartmentalization is the main difference compared to eukaryotes. In prokaryote cells the ribosomes are scattered in the cytoplasm, so it is correct to say that the protein synthesis in prokaryotes takes place in the cytoplasm. In eukaryotes the ribosomes also reside in the cytoplasm, but could be also found bound to the endoplasmic reticulum (ER). The membranes of the endoplasmic reticulum form a complex and continuous network in the inner core of the cytoplasm and is both to the outer membrane of the nucleus and with the plasma membrane.
