About this episode
The episode explores how DNA is constantly changing and the implications of these mutations on our understanding of disease and genetic therapy.
We tend to think of the DNA strands that contain our genetic code as consistent, stable units. But in reality, the cells that make up our bodies are constantly replicating and changing. Even as you read this sentence, in fact, the genes within your cells are mutating. So, what causes these mutations and what’s the impact? Science writer Roxanne Khamsi examines the answers in her new book, Beyond Inheritance . Today on the show, she gets into how scientists examine these mutations, how they’ve shifted our understanding of disease and what the future of genetic therapy could entail.
