DNA structure and function. DNA is the information molecule. It stores instructions for making other large molecules, called proteins. These instructions are stored inside each of your cells, distributed among 46 long structures called chromosomes. These chromosomes are made up of thousands of shorter segments of DNA, called genes.

And you go to 1944 and Avery, McCarty, and MacLeod are able to show some pretty good evidence that the actual principle, the thing that was left in that heat-killed bacteria, was probably DNA. And then we get even more conclusive evidence with the experiments of Hershey and Chase and we have a whole video on this.
