Cracking the Code of Life, Chapter 12: Finding Disease Genes
Chapter 12 of a two hour 16 part presentation. Running time 04:06. This chapter explores how scientists use the human genome to make the connection between a disease and a gene. Scientists use families to find the specific genes that cause a particular disease and Iceland is a perfect place to do that. As the company DeCODE gears up to create a giant DNA database using the Icelandic family tree...

Cracking the Code of Life, Chapter 9: Finding Cures is Hard
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...

Cracking the Code of Life, Chapter 3: One Wrong Letter
The third chapter of a two hour program. (running time 08:57) Tay Sachs disease results from a single base pair change causing the malfunction of a critical protein that breaks down fat in the brain. As fat builds up, and crushes critical cells in a child's brain, they lose motor skills, the ability to talk, swallow, and see. This chapter explores two couples with children with this devestating...
