Why are some cancer cells immortal? What can we learn about aging from a lobster? Why does a gene from a human work in a bacteria? The answers lies in genetics. In this episode I explain how understanding the basics of DNA replication, the genetic code, and mutations improves our lives from treating cancer, slowing aging, to making medicines.
