  • Dengue Virus Enters a Cell

    Dengue Virus Enters a Cell

    Animation

    (1 min 33 sec) Infection begins when the dengue virus uses receptors on an immune cell's surface to gain entry and release its genome.

  • Structure of Dengue Virus

    Structure of Dengue Virus

    Animation

    (1 min 3 sec) The dengue virus's outer envelope proteins form symmetrical units and overlay the lipid envelope, capsid, and the RNA genome.

  • Dengue Virus Life Cycle

    Dengue Virus Life Cycle

    Animation

    (4 min 12 sec) Dengue virus has sophisticated mechanisms for entering a cell, for replicating its RNA genome, and for translating proteins.

  • Viral Geometry and Structural Diversity

    Viral Geometry and Structural Diversity

    Animation

    The geometric structures of viruses are beautiful and can be used, along with genomic information, to identify them.

  • HIV life cycle

    HIV life cycle

    Animation

    (4 min 52 sec) How HIV infects a cell and replicates itself using reverse transcriptase and the host's cellular machinery.

  • AZT blocks reverse transcriptase

    AZT blocks reverse transcriptase

    Animation

    (1 min 46 sec) HIV's reverse transcriptase mistakes AZT for thymidine. Once incorporated, AZT stops reverse transcription.

  • U.S. AIDS epidemic

    U.S. AIDS epidemic

    Animation

    A visual representation of the U.S. AIDS epidemic from 1981 to 1997. Each dot represents 30 cases.

  • Using p53 to Fight Cancer

    Using p53 to Fight Cancer

    Animation

    (1 min 2 sec) This animation demonstrates how cancerous cells could be destroyed using a modified virus.

  • Recombination of Viral Genome

    Recombination of Viral Genome

    Animation

    (3 min 5 sec) When two different strains of influenza infect a single cell, their genetic material can mix freely, resulting in a new third strain of influenza.

  • Viral Lifecycle

    Viral Lifecycle

    Animation

    (1 min 8 sec) Delivering a single virus to a cell allows the virus to infect the cell, replicate, and give rise to many progeny viruses. These viruses can then infect many neighboring cells. Also available in Spanish.
