Answer:
Transcription & translation (Ans. A)
Explanation:
Prokaryotic organisms do not have membrane-bound organelles such as the nucleus, thus the process of transcription & translation occurs in the cytoplasm. Also because of the need for rapid life cycle, the mRNA molecules start to be made, & their ribosomes are ready to start making proteins more rapidly than Eukaryote, thus the process of the couple is quicker.
In eukaryotic organisms, transcription process start (happens) inside the nucleus of the cell and translation process can't start until the mRNA is transported out from the nucleus into the cytoplasm.
