Q
Intro 1 History/Mathematics
A
-but the frequency of mutation to resistance is TOO LOW?!
10^-6 =probability of independent mutation in any given gene
-2 or 3 independent mutation events: INCREDIBLY SMALL NUMBER, RARELY HAPPENS IN NATURE

Q
Intro 2-AHA!!

- multiple resistance already exist within different bacteria in the population
- so to acquire resistance just ACQUIRE large pieces of DNA from other bacteria or from bacterial viruses (bacteriophages)

2. conjugation
3. transduction - *wont be happening concurrently-duhhh
