Why is the term appropriate given to Griffiths observations is transformation?

The term "transformation" is appropriate for Griffiths' observations because it describes the process by which genetic material from one organism can change the characteristics of another organism. In his classic experiments with Streptococcus pneumoniae, Griffith demonstrated that non-virulent bacteria could become virulent when exposed to heat-killed virulent strains, indicating a transfer of genetic information. This process of acquiring new traits through the uptake of foreign DNA is fundamentally what transformation entails in a biological context.
