Those experiments proved that DNA, not protein, is the genetic material. They built a ladder of evidence: Griffith found a 'transforming principle,' Avery's team pinned it to DNA, and Hershey-Chase used viral tags to confirm it.
But from where I stand, in a lab staining gels in the Himalayan cold, what they truly proved is that the answer is often simple and stubborn, hiding in plain sight. It's like my mamu's dye recipe—everyone argued over the mordant, but the secret was just the temperature of the water. My own PCR failures taught me to trust the basic template, not the fancy additives. The obvious molecule was the right one all along.
