1 ene 1944 año - The Avery, McCarty, MacLeod experiment took place.

Descripción:

This was an experimental demonstration that proved that DNA is the substance that causes bacterial transformation and hereditary genes. This was revolutionary because this discovery contested the popular belief that proteins carried genetic information. By applying lipases, proteases, and ribonuclease to the transforming principle, the scientists isolated this principle to be DNA. Overall, this experiment proved that DNA coded and transmitted genetic material.
