Nuclear membrane', 'role': 'user'}, {'content': "Answer: A \nExplanation: Unlike eukaryotic cells in which the electron transpo system is located on mitochondria, the electron transpo system of bacteria is located on the cytoplasmic (plasma) membrane. Mesosomes and polyribosome DNA aggregates are also found in bacterial cells and function in cell division and protein synthesis, respectively. Bacteria do not have mitochondria or membrane-bounded nuclei. Ref: Brooks G.F. (2013). Chapter 2. Cell Structure. In G.F.
