Do you know, by chance, how scientists discovered the make-up of DNA? Was it via a microscope and if so, what type of microscope allows you to view the structure of DNA?

asked by will
  1. I believe they detected the proteins involved, they knew those long before they even knew what DNA exactly did or looked like.
