Transformation is important in bacterial pathogenicity because
A.
it allows uptake of DNA that can homologously recombine into the bacterial chromosome and change virulence characteristics
B.
it kills recipient cells and prevents future cell invasion
C.
it enhances site-specific recombination that turns on virulence factor genes
D.
it causes transpositions to occur at high frequency that can kill virulent bacteria
