Question

Which new phenomenon did Griffith focus on during his work with pneumonia-causing bacteria and mice? would it be A. Transfer of Genetic material through conjugation. B. Transfer of genetic material through transformation. C. Transfer of genetic material through transduction.

Answer 1

the answer is B

hope this helps

Answer 2

Griffith's experiment described the new phenomenon of transfer of the genetic material by transformation. In this process, bacteria can transfer the DNA by transformation, and that is why in the Griffith's experiment, the mice treated with heat killed smooth strain plus normal rough strain, got killed. The DNA from heat killed smooth strain transferred to the rough DNA possessing bacteria, and made it virulent, which caused mice death.
