Some New Tricks With DNA

The 1970s and 80s saw the invention of ingenious new ways to manipulate DNA, which remain the cornerstone of today's genetic revolution, including the Human Genome Project. We begin with a scientist/magician demonstrating six simple tricks with DNA. Using these as building blocks, the more comple...

Understanding The Book of Life

Reading the Book of Life was just the first step. The ultimate goal is to understand how it works. We are guided towards this new genetic horizon by Francis Collins and Craig Venter, the leaders of the two competing teams that first sequenced the human genome. The initial task is to separate out ...

The DNA Obsession

Beginning with its discovery in a gothic German castle, we follow the scientific surprises as DNA beat out protein, the more logical candidate, as the stuff of the gene. Joshua Lederberg pays tribute to the work of Oswald Avery, the Canadian-born scientist who first proved it was DNA and the impa...

The Gene Machine

We follow the steps by which the discovery of the double helix in 1953 quickly led to our understanding of how a gene produces a protein, using messenger RNA as the intermediary. The basics of transcription and translation are clearly explained using creative animation. Then in the 1960s came the...

Microscopes and Mutants

The actions of chromosomes during mitosis, meiosis and fertilization, as discovered in 19th century Germany, are explained in this video. These microscopic findings, together with the rediscovery of Mendel's long-lost research in 1900, gave birth to the Chromosomal Theory of Heredity. Sex chromos...

Reading the Book of Life

The human genome sequence was the finish line for another famous race in genetics, which led to a historic White House press conference. The leaders of this epic effort, including Francis Collins, Craig Venter, Eric Lander, John Sulston and Sydney Brenner, explain its origins, how it was done and...

Peas in a Pod

This episode tells the story of genetics from ancient times to its true scientific beginnings in the 19th century. Humorous animation and other creative visuals illustrate the unsuccessful efforts of Aristotle, Darwin and others to solve the age-old puzzle of heredity. The focus then shifts to Gr...

The Seeds of a New Era

This episode examines the science of genetically modified crops and foods. It begins by explaining, through creative animation, the actual process by which a foreign gene is introduced into a plant. It then examines the actual benefits and risks of the two types of genes currently added to GM cro...

Is There Life on Mars?

Series: Nova
This video examines Mars. NASA's two robot explorers, Spirit and Opportunity, first landed on Mars in January, 2004. The rovers were expected to function for the initial 90-Martian-day (sol) primary mission. Since that time, the Rovers have lasted 16 times longer and traveled 20 times farther. Th...
