The transforming principle in Griffith's experiment was detected _______.
Options:
Answer:
A
Solution:
In Griffith's experiment, the transforming principle was detected when heat-killed S-strain (virulent) bacteria were mixed with live R-strain (non-virulent) bacteria and injected into mice.
The mice died of pneumonia, and live S-strain bacteria were recovered from their blood. This indicated that some 'transforming principle' from the heat-killed S-strain had transformed the live R-strain into the virulent S-strain.
Answer: When heat killed S-strain of S. pneumoniae were mixed up with the R-strain.
