Document Summary

Needle like protrusions that comes out of cell. Allows bacteria to make poisonous proteins in cytoplasm so when injects it in host cell injects poison and kills the host cell. Made of diff proteins embedded in cell walls **** Hollow and allow sprotiengs to go up and into the cytoplasm of host cell. Only made at 37c not done/wanted to do so in flea. One of the only prof biologists that doesn"t accept evolution (darwinian) Composed of diff proteins and have to be put together in specific way. Each protien has its own gene =many genes in structure required. Proposes that structure is too complex to evolve by itself. Argues that its impossible must"ve been intelligent creature that created it. Hypothesis is an explanation based on knowledge/experience. ****scientific hypothesis must be testable & falsifiable. Issue with intelligent design: can"t be tested=not scientific; but is hypothesis (not scientific hyp) Injectisome now evidence that flagellum developed from simple structure.
