  • DNA Sequence Technology Improves Cancer Treatment

    DNA Sequence Technology Improves Cancer Treatment

    Clip

    (2 min 6 sec) Dr. Charles Sawyers discusses how the identification of most cancer genes could transform cancer into a chronic disease.

  • Genetics of Human Origins and Adaptation

    Genetics of Human Origins and Adaptation

    Lecture

    (58 min 31 sec) Genetic evidence shows that humans evolved in Africa and continue to evolve.

  • The Virus Hunter's Toolkit

    The Virus Hunter's Toolkit

    Lecture

    (58 min 33 sec) New technologies like the Virochip harness DNA's properties to identify and fight new viruses.

  • Shotgun sequencing

    Shotgun sequencing

    Animation

    (1 min) In shotgun sequencing many copies of the entire genome are "blown up" into millions of small fragments. Each small fragment is sequenced. Powerful computers then assemble the individual fragments into the original configuration. Repeat sequences pose a problem for this approach because their sizes can be much larger than the small fragments.

  • Human genome sequencing

    Human genome sequencing

    Animation

    (1 min 49 sec) The public Human Genome Project started by identifying unique marker sequences distributed throughout the genome. Then, many copies of a small section of DNA were randomly cleaved into smaller fragments, and each small fragment was sequenced. Because there were originally many copies of the DNA in question, many fragments represented the same part of the genome. These were aligned by identifying overlapping regions of the sequence, and then they were assembled into the original DNA.

  • Scanning Life's Matrix: Genes, Proteins, and Small Molecules

    Scanning Life's Matrix: Genes, Proteins, and Small Molecules

    Lecture

    In four presentations, Stuart L. Schreiber, PhD, and Eric S. Lander, PhD, open a window onto the fast-paced world of genomic science and chemical genetics.
