Question

Quizplus · Accepted Answer

The experiments using the DNA-binding dye provided circumstantial evidence that DNA is the genetic material because it showed a correlation between the amount of DNA present and the number of chromosomes, which are known to carry genetic information. However, further experiments were needed to definitively prove that DNA is the genetic material.
