1	Our hypothesis was that [fast-mutating strain] E938, which is Mut-, would show increased mutation over [the slow-mutating] strain E939.
2	This hypothesis was supported by both our individual and class data.
3	The increased mutation rate and survival of E938 can be attributed to the faulty DNA repair of the Mut− strain.
4	Increased mutation rate allows more bacteria of this strain to gain the traits necessary for survival on the rifampicin plates.
5	E938 also adapts better for the use of lactose as an energy source on the MacConkey agar.
