Prokaryotes vs. Eukaryotes âDifferences. Eukaryotes as well as protists, a miscellany group made up of eukaryote-like plant, animal and fungi missing one or more characteristics to be defined as purely eukaryotic, differ greatly from prokaryotes in structure.
It is now clear that prokaryotic cells possess actin and that a dynamic actin-like cytoskeleton is involved in a variety of essential cellular processes in bacteria. These functions, like those of the eukaryotic actin cytoskeleton, require the targeting and accurate positioning of proteins and molecular complexes.he discovery of the prokaryotic homologues of actin (as well as of other cytoskeletal elements in bacteria) has forced a radical rethink about the origin of the cytoskeleton and revolutionized our view of bacterial cell architecture.
Widely used component: Restriction enzymes: are DNA-cutting enzymes found in bacteria.They are molecular scissors that cut DNA into fragments at specific sites in their sequence.Many bacteria make these enzymes to protect themselves from foreign DNA brought into their cells by viruses.g: Eco RI obtained from Escherichia coli RY 13 Plasmids: are naturally occurring, stable genetic elements found in bacteria. Plasmids almost always exist and replicate independently of the chromosome of the cell in which they are found and hence used in cloning techniques and are efficient cloning vectors.
