41. These processes occur in eukaryotes but not in prokaryotes . 42. In prokaryotes , splicing is done by autocatalytic cleavage or by endolytic cleavage. 43. Hairpin loops are often elements found within the 5'UTR of prokaryotes . 44. In any case, prokaryotes do not have mitochondria and survive just fine. 45. However, prokaryotes do possess some internal structures, such as prokaryotic cytoskeletons. 46. Two types of positive phototaxis are observed in prokaryotes . 47. MS channels are ubiquitously expressed in the membrane of prokaryotes suggesting their significance. 48. The topo I of both prokaryotes and eukaryotes are the type I topoisomerase. 49. In prokaryotes and eukaryotic microorganisms it is involved in the biosynthesis of arginine. 50. The protein domain has been found to be present in both prokaryotes and eukaryotes
