Multiple Choice

Another way that one could demonstrate transformation in bacteria would be to extract DNA from

• A)an ampicillin- sensitive strain and mix with cells of an ampicillin- resistant strain.
• B)both S and R strains and mix to allow recombination to take place.
• C)a S strain and mix with cells of a R strain.
