Prokaryotes Lack Membrane-Enclosed Organelles and Thus Do Not Have Nuclei

Question

Prokaryotes lack membrane-enclosed organelles and thus do not have nuclei.Therefore,prokaryotic
A) cells are unable to undergo transcription and translation.
B) cells do not need to undergo translation.
C) cells do not need to undergo transcription.
D) transcription and translation both take place in the cytoplasm.

Accepted Answer

Since prokaryotes lack a nucleus, both transcription (the process of creating mRNA from DNA) and translation (the process of synthesizing a polypeptide chain from mRNA) must occur in the cytoplasm. Prokaryotic DNA is directly converted to mRNA, which can then be translated into protein by ribosomes.
