Did you know that thousands of mutations occur on our DNA every second? In this episode I discuss what happens when our DNA is damaged, and more specifically, what happens when our body fails to repair mutations on our DNA, leading to disease. I talk about how mutations on our DNA can either cause disease or increase our chances of survival. I talk about what makes someone genetically prone to a disease and what it means for someone to be genetically prone to a certain disease. I talk about how mutations can be beneficial and detrimental simultaneously, which is what is seen in sickle cell disease. I discuss how advances in healthcare allows us to examine which diseases we are genetically prone to, like breast cancer, and how these tests allow us to take steps to prevent the disease from being expressed. I also talk about the promise of genetic engineering and CRISPR technology and how they can be applied and implemented to potentially cure diseases like sickle cell disease and muscular dystrophy.
