The Pneumococcus experiment proves that

1. DNA is the genetic material
2. Bacteria undergo binary fission
3. Bacteria do not reproduce sexually
4. RNA sometime controls the production of DNA and proteins

Correct answer: DNA is the genetic material

Solution

The Pneumococcus transformation experiment showed that a heritable “transforming principle” from one bacterium could change another bacterium’s traits. Later work identified that transforming principle as DNA, proving DNA carries genetic information.
