Txhawm rau ua qhov no, pab pawg tau hloov kho DNA ntawm Escherichia coli kab mob kom nws tsim cov protein prothrodopocin hauv nws cov kab me me - cov "tails" uas cov kab mob siv rau locomotion. Sensitive rau lub teeb, nws yog siv nyob rau hauv ib co kab mob los tsim lub zog.

"Zoo li cov neeg taug kev qeeb qeeb thaum ntsib cov neeg coob coob lossis tsheb daig hauv kev tsheb, cov kab mob yuav siv sij hawm ntau dua ua luam dej hauv thaj chaw qeeb dua li thaj chaw nrawm dua," tus kws sau ntawv Dr Giacomo Frangani tau hais.
