    Seed Dispersal in Tropical Forests

    Activity

    In this activity, students use data from published studies to understand patterns of seed dispersal and apply these ideas to the design of a conservation area.

  • Role of p53 in the Cell Cycle

    Role of p53 in the Cell Cycle

    Data Point

    Researchers investigated the role of p53 in cell cycle regulation by genetically engineering a cell line with deleted copies of the p53 gene. They exposed the cell lines to DNA-damaging radiation and observed how this exposure impacted mitosis.

  • The Search for a Mutated Gene

    The Search for a Mutated Gene

    Scientists at Work

    (8 min 54 sec) How do you identify the disease-causing mutation in a patient with an inherited disease? This video illustrates the steps involved—testing for genes that are the “usual suspects,” searching for mutations in novel genes, and assessing links between genotype and phenotype.
