This animation shows how mutations in an ion channel protein lead to the genetic disease cystic fibrosis. The animation also discusses how research on this protein has been used to develop treatments for the disease.
A number of questions are embedded within the short film The Making of the Fittest: The Birth and Death of Genes, which illustrates how gene duplications and mutations have led to remarkable physiological adaptations in Antarctic fish.
This lesson supports concepts covered in the film The Birth and Death of Genes. After watching the film and reading a couple of scientific passages, students explain how understanding about icefish adaptations might help develop treatments for health conditions.
