Vedclass · Answer

(B) In Frederick Griffith's experiment,he used two strains of Streptococcus pneumoniae: the $S$-strain (smooth,virulent) and the $R$-strain (rough,non-virulent).When heat-killed $S$-strain bacteria were mixed with live $R$-strain bacteria and injected into mice,the mice died.Griffith observed that the live $R$-strain bacteria had been transformed into virulent $S$-strain bacteria.This process,where the genetic material from the heat-killed $S$-strain was taken up by the live $R$-strain,is known as bacterial transformation.
