Predict what would happen to a motile bacterium undergoing chemotaxis if the Mot proteins suddenly ceased to function
What will be an ideal response?
Answer: The function of Mot proteins should be described producing the rotation of the flagella. This would probably allow flagella to form, but they would not be able to rotate. The bacterium would not be able to move, but the flagella would still look normal.
