Sample Question
The significance of Fred Griffith's experiment in which he used two strains of Streptococcus pneumoniae is that

Harmless and pathogenic bacteria function differently in mice than in other organisms.

It demonstrated that harmless bacteria can become transformed into disease-causing bacteria by some association with pathogenic bacteria.

It established that pure DNA extracted from disease-causing bacteria transformed harmless strains into killer strains.

Dead cells lose their genetic information.
