Chapter 9 of a 2 hour program. Running time 08:07. The discovery of the gene for cystic fibrosis(CF) leads to hope of a cure. This chapter explores the changes in a person's DNA and subsequent changes in their proteins which ultimately cause CF. This chapter uses 3D computer models to show how proteins are structured and discusses why shape is important to proteins. In addition, the question is...
