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.
First discovered by scientists studying the immune system of bacteria (specifically E. coli), CRISPR is based on the way the bacteria defends against virus infections. It does this by creating RNA that, when combined with a gene editing nuclease called Cas9, can target the DNA of an invading virus and disable it by cutting its gene sequence.
