    Teacher Guide: DNA
    Classroom Resource
    Topics include: DNA structure and function, DNA replication, damage to DNA and eukaryotic chromosomal structure.
    Teacher Guide: Evolution
    Classroom Resource
    Topics include: natural selection, artificial selection, population genetics, human adaptations and evolution, and phylogenetics.
    Classroom Activities: Natural Selection and Adaptation
    Classroom Resource
    The following classroom-ready resources complement The Making of the Fittest: Natural Selection and Adaptation, which describes the physical and genetic evolutionary changes in rock pocket mouse populations.
    Classroom Activities: Natural Selection in Humans
    Classroom Resource
    The following classroom-ready resources complement The Making of the Fittest: Natural Selection in Humans, which describes the connection between malaria and sickle cell anemia—one of the best-understood examples of natural selection in humans.
    Sorting Seashells
    Click & Learn
    Explore principles of taxonomy by sorting seashells according to their morphological characteristics and constructing an evolutionary tree.
    Paired DNA strands
    Animation
    DNA has a double helix structure. If untwisted, DNA looks like two parallel strands. Each strand has a linear sequence of A, C, G, and T. The precise order of the letters carries the coded instructions. One strand is a complementary image of the other: A always pairs with T, and C always pairs...
    Gender Testing of Athletes
    Click & Learn
    Learn why verifying a person's gender may be harder than you think.
    Molecular Genetics of Color Mutations in Rock Pocket Mice
    Classroom Resource
    A lesson that requires students to transcribe and translate portions of the wild-type and mutant rock pocket mouse Mc1r genes and compare sequences to identify the locations and types of mutations responsible for the coat color variation described in the film.
    The Molecular Evolution of Gene Birth and Death
    Classroom Resource
    An advanced lesson that describes the role of mutations in the birth and death of genes. It includes background information, examples, video clips, and animations.
    Population Genetics, Selection, and Evolution
    Classroom Resource
    A hands-on activity that uses simulations with beads to teach students about population genetics, the Hardy-Weinberg principle, and how natural selection alters the frequency distribution of heritable traits. 
    Mendelian Genetics, Probability, Pedigree, and Chi-Square Statistics
    Classroom Resource
    A lesson that requires students to work through a series of questions pertaining to the genetics of sickle cell disease and its relationship to malaria. These questions will probe students' understanding of Mendelian genetics, probability, pedigree analysis, and chi-square statistics.
    Classroom Activities: Pedigree Analysis Activity
    Classroom Resource
    To accompany the lecture series Learning from Patients: The Science of Medicine.
    Using Genetic Crosses to Analyze a Stickleback Trait
    Classroom Resource
    A hands-on activity in which students analyze the results of genetic crosses between stickleback fish with different traits.

    Regulation of Sex Determination in C. elegans
    Video Clips
    A demonstration by Dr. Meyer showing how a balance of molecular elements trigger genetic pathways that determine the sex of a C. elegans worm.
    Rett Syndrome Mouse
    Video Clips
    Dr. Zoghbi shows how a mouse that has been given the gene responsible for Rett syndrome exhibits some of the same neurological symptoms as human Rett patients.
    SCA1 Mouse on Rotarod
    Video Clips
    Dr. Zoghbi demonstrates how mice that have been given the gene responsible for spinocerebellar ataxia 1 (SCA1) are tested on a device called a rotarod to quantify the amount of ataxia present.
    Reading Genes and Genomes
    Lectures
    Dr. Eric Lander takes us on a tour of this remarkable genetic century, describing the rapid advances in DNA sequencing technologies and information science.
    Human Genetics: A New Guide for Medicine
    Lectures
    Dr. Lander explores human genetic variation and how it may affect individual susceptibility to certain diseases.
    Research Mechanics: Putting the Brakes on Cancer
    Lectures
    Although there are numerous kinds of cancer, all stem from alterations that allow cell division to outstrip cell demise.
    Chaos to Cure: Bringing Basic Research to Patients
    Lectures
    The identification of hundreds of genes involved in the formation and spread of cancer is leading to promising new methods for diagnosis, prevention, and treatment.
    A Healthy Nervous System: A Delicate Balance
    Lectures
    Mutations in key genes can lay waste to the nervous system. By studying large families predisposed to developing these genetic disorders, scientists can identify the responsible altered gene.
    The Strength of Families: Solving Rett Syndrome
    Lectures
    Girls with Rett syndrome develop normally for about 18 months and then begin to regress. With the help of affected girls and their families, Dr. Zoghbi and her collaborators searched for the gene responsible for this neurological disorder.
    Bioethics Discussion
    Lectures
    Genetic research benefits health, but also raises thorny ethical issues.
