41. Little is known about DNA or the origins of reproduction in prokaryotic or eukaryotic cells. 42. Restriction endonucleases are used as defense mechanisms in prokaryotic organisms in the restriction modification system. 43. The C-terminal region of the prokaryotic topoisomerases has been solved for multiple species. 44. G418 blocks polypeptide synthesis by inhibiting the elongation step in both prokaryotic and eukaryotic cells. 45. Prokaryotic cells are usually singletons, while eukaryotic cells are usually found in multicellular organisms.46. Membranes serve diverse functions in prokaryotic cells. 47. The EzTaxon database contains sequences of type strains of prokaryotic species with validly published names. 48. Its host itself is a prokaryotic pathogen for citrus plants, causing Citrus stubborn disease. 49. Analysis showed that the small size of prokaryotic cells is essential for successful growth under hypergravity. 50. An analysis by Salzberg identified 40 potential genes laterally transferred into the genome from prokaryotic organisms.
