A) Prokaryotes only.
B) Eukaryotes only.
C) Unicellular organisms only.
D) Multicellular organisms only.

In prokaryotes, transcription and translation occur simultaneously in the cytoplasm, which means protein synthesis can occur while the mRNA molecule is being synthesized. In contrast, in eukaryotes, transcription occurs in the nucleus and mature mRNA must be transported to the cytoplasm for translation to occur. Thus, in eukaryotes, protein synthesis cannot occur while the mRNA molecule is being synthesized. The presence of unicellular or multicellular organisms is not relevant to this question.
