Which of the following is a unique characteristic of prokaryotic cells?
Correct answer: D. mRNA translation simultaneous to transcription
- A. Lack of a cytoplast
- B. Presence of a cell wall
- C. Inability to create proton gradients
- D. mRNA translation simultaneous to transcription
Explanation
Prokaryotes are unicellular organisms that lack membrane-bound structures, including the nucleus, which is the hub of 'Transcription'. This makes it improbable for 'Translation' and 'Transcription' to occur simultaneously.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
