In this video segment adapted from NOVA scienceNOW, scientists discuss a family of genes called FOXO that can significantly extend life span in worms—and in humans.
In this video excerpt from NOVA, find out how whole genome sequencing saved the life of Alexis, a fraternal twin who was originally diagnosed with cerebral palsy but, in fact, had an even rarer genetic condition.
In this animation produced by WGBH and Digizyme, Inc., see how molecules of DNA are separated using gel electrophoresis, and how this process enables scientists to compare the molecular variations of two or more DNA samples.
In this video segment adapted from NOVA scienceNOW, learn how what you eat, drink, or smoke may affect the instructions your epigenomes send to your genes, and as a result, change how your DNA is expressed.
In this video excerpt from NOVA, learn about the advantages, disadvantages, and ethical implications of preimplantation genetic diagnosis, or PGD, a technique used to screen embryos created through in vitro fertilization for diseases.
This video segment from NOVA: "The Killer's Trail" investigates the potential for DNA evidence to solve murder cases, even those from the distant past.
In this video excerpt from NOVA, find out how the discovery of a gene defect has led to the development of a new drug to treat patients with cystic fibrosis.
The shared set of genes for body segments, possessed by all animals, are discussed in this video segment from Evolution: "Great Transformations."
This narrated animation from Interactive NOVA: "The Secret of Life" illustrates DNA replication.
This video segment from NOVA: "Cracking the Code of Life" looks at the meaning and significance of the effort to decode the human genome.
In this video segment adapted from NOVA scienceNOW, learn about RNAi's potential to treat a wide range of genetic and infectious diseases.
This animation adapted from Garland Science Publishing takes a close look at the DNA double helix and its individual components, describing their chemical structures and how they function together to make the DNA molecule unique.
This video segment adapted from NOVA reveals how junk DNA helped solve an evolutionary mystery: Why do certain species of fruit flies have wing spots while others don't?
Marilyn Havlik leads students through a simulation of the Hardy-Weinberg Principle to develop their understanding of population genetics.
This video adapted from the University of Leicester demonstrates the proper use of different-sized micropipettes to measure precise volumes of liquid in the lab.
