Question

Frederick griffith was one of the leading scientists looking at the genetic role of dna. He was working on two strains of streptococcus pneumoniae: the rough strain (r) did not cause pneumonia, but the smooth strain (s) did. When griffith heat-killed the s strain and gave both the heat-killed s strain and the r strain to mice, the mice developed pneumonia and died. What happened in this experiment that caused the mice to develop pneumonia?

Answer 1

Answer:

the heat killed s strain gave his genetic material to r strain who was not a cause of pneumonia. hence due to this the mice died
