Webflagellum, plural flagella, hairlike structure that acts primarily as an organelle of locomotion in the cells of many living organisms. Flagella, characteristic of the protozoan group … WebApplication: • Prokaryotes divide by binary fission. Binary fission is a form of asexual reproduction used by prokaryotic cells. In the process of binary fission: The circular DNA is copied in response to a replication signal. The two DNA loops attach to the membrane. The membrane elongates and pinches off (cytokinesis), forming two cells.

WebBinding of c-di-GMP by DgrA leads to destabilization of the flagellar motor protein FliL. Though the mechanism of action is not known, it does not act at the level of fliL transcription, suggesting that DgrA-mediated motility disruption functions on already-formed flagella.
