About this episode

Dr. Linda Chelico discusses the dynamic nature of DNA and its implications for cancer treatments.

DNA carries the code for carrying out biological life, yet DNA is an unstable molecule. The reality is that DNA in all organisms is in a dynamic state with its environment, constantly becoming damaged and undergoing processes for damage reversal and repair. In this TEDx talk, Dr. Linda Chelico, a professor who research spans biochemistry, virology, and cancer biology, discuss how understanding DNA can lead to new insights on cancer treatments.
