The Dam methylase is responsible for methylating the adenine base in GATC sequences in Escherichia coli. Imagine two

A) Both of the strains
B) Neither of them
C) Only the first strain
D) Only the second strain
E) coli strains, one without any active Dam methylase, and the other with a hyperactive version of the enzyme that operates faster than the wild-type enzyme. Which of these strains would you expect to show a "mutator" phenotype?
