The correct answer is ribosomes. E.coli is a Gram-negative bacterium, therefore it is a prokaryotic organism. Prokaryotes' main characteristic which also differentiates them from the eukaryotes is the fact that they do not have an organised nucleus and other membrane-bound organelles. Prokaryotes' cytoplasm contains ribosomes and this is one of the things that they have in common with the eukaryotes. Ribosomes are molecular machines which are apparent in all living cells. They are very important because this is where protein synthesis occurs.
The presence of ribosomes can be observed in both e. coli and other
prokaryotes that have in common with all eukaryotes. E.coli is a unicellular
bacteria that belongs to prokaryotes, and these prokaryotes do not contain any
organized nucleus or specialized organelles and its genetic material includes
genomic DNA and plasmid DNA.
