TED-Ed: What happens when your DNA is damaged? - Monica Menesini
The DNA in just one of your cells gets damaged tens of thousands of times per day. Because DNA provides the blueprint for the proteins your cells need to function, this damage can cause serious issues-including cancer. Fortunately, your...
