  • How Species Coexist

    How Species Coexist

    Science Talks

    (27 min 25 sec) Large herbivores in the African savanna coexist by partitioning ecological niches by time, space, and diet.

  • Mapping Genes to Traits in Dogs Using SNPs

    Mapping Genes to Traits in Dogs Using SNPs

    Activities

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

  • Using DNA to Explore Lizard Phylogeny

    Using DNA to Explore Lizard Phylogeny

    Activities

    This activity supports the film The Origin of Species: Lizards in an Evolutionary Tree. Students are guided to sort the lizard species by appearance, then generate a phylogenetic tree using the lizards’ DNA sequences to evaluate whether species that appear similar are closely related to each other.

  • Bacterial ID Virtual Lab App

    Bacterial ID Virtual Lab App

    Apps and eBooks

    Learn about the science and techniques used to identify different types of bacteria based on their DNA sequences

  • Virochip DNA Microarray

    Virochip DNA Microarray

    Click & Learn

    Answer interactive questions to explore the logic of the Virochip microarray design, particularly how evolutionary relationships can be used to detect new viruses.

  • DNA Sequence Assembly

    DNA Sequence Assembly

    Click & Learn

    Learn the principles of how DNA is sequenced and assembled into whole genomes using the Sanger method, shotgun sequencing, or ultra-deep sequencing.

  • Leading-Edge Bioinformatics

    Leading-Edge Bioinformatics

    Clips

    (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

    Animations

    (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.

  • How to Analyze DNA Microarray Data

    How to Analyze DNA Microarray Data

    Click & Learn

    DNA microarrays, or gene chips, are an important new technology for genomic research. Learn how researchers use computing to analyze and interpret the huge datasets generated by microarray experiments.
