Question

Quizplus · Accepted Answer

Griffith's studies demonstrated the phenomenon of bacterial transformation, where genetic material (DNA) from one bacterium can be taken up by another bacterium and change its phenotype. This was a crucial discovery in understanding the role of DNA as the carrier of genetic information, but it did not prove that DNA is the genetic material of all organisms, nor did it address the topic of bacterial reproduction.
