  • Mapping Genes to Traits in Dogs Using SNPs

    Mapping Genes to Traits in Dogs Using SNPs

    Activity

    In this hands-on genetic mapping activity students identify single nucleotide polymorphisms (SNPs) correlated with different traits in dogs.

  • Dog Genomics and Dogs as Model Organisms

    Dog Genomics and Dogs as Model Organisms

  • Solving SARS and Other Viral Mysteries

    Solving SARS and Other Viral Mysteries

    Lecture

    (58 min 33 sec) The SARS epidemic was successfully halted by a global research effort to identify a new virus.

  • 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.

  • Leading-Edge Bioinformatics

    Leading-Edge Bioinformatics

    Clip

    (6 min 36 sec) Peter Skewes-Cox, and Dr. Graham Ruby, both in the DeRisi lab, explain state-of-the-art DNA sequencing and bioinformatic technologies.

  • 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.
