  • Lactase Film with Quiz

    Lactase Film with Quiz

    Interactive Video

    (14 min 52 sec) Embedded quiz modules test students’ understanding as they watch a short film that explores the evolution of the ability to digest lactose as adults (lactose tolerance) and the genetic changes associated with the trait.

  • How We Get Our Skin Color

    How We Get Our Skin Color

    Animation

    (3 min 32 sec) This engaging animation shows how human skin cells produce the pigment melanin, which gives skin its color. 

  • These Limbs Are Made for Walkin'...

    These Limbs Are Made for Walkin'...

    Image of the Week

    ... but that's not all they'll do. Several genes determine the diverse shapes and functions of crustacean appendages. 

  • Lactose Intolerance: Fact or Fiction

    Lactose Intolerance: Fact or Fiction

    Activity

    Students evaluate and discuss several statements about lactose intolerance and evolution before and after watching the film. Also available in Spanish.

  • Got Lactase? Blood Glucose Data Analysis

    Got Lactase? Blood Glucose Data Analysis

    Activity

    Students interpret the results of two different tests for lactase persistence.

  • Modeling the Regulatory Switches of the Pitx1 Gene in Stickleback Fish

    Modeling the Regulatory Switches of the Pitx1 Gene in Stickleback Fish

    Activity

    A hands-on activity in which students interpret molecular diagrams and build physical models of eukaryotic gene regulation.

  • The Making of the Fittest: Got Lactase? The Co-evolution of Genes and Culture

    The Making of the Fittest: Got Lactase? The Co-evolution of Genes and Culture

    Short Film

    (14 min 52 sec) Follow human geneticist Spencer Wells, Director of the Genographic Project of the National Geographic Society, as he tracks down the genetic changes associated with the ability to digest lactose as adults. Also available in Spanish.

  • Teacher Guide: AP Biology

    Teacher Guide: AP Biology

    Teacher Guide

    This guide correlates all the resources available on the Holiday Lectures on Science DVDs and throughout the BioInteractive.org website to specific Big Ideas, Enduring Understandings, and Essential Knowledge threads of the new AP® Biology Curriculum Framework. 

  • Cytoplasmic Factors

    Cytoplasmic Factors

    Animation

    (57 sec) Cytoplasmic factors play a significant part in determining how a cell develops. This segment discusses their importance in turning the appropriate genes on and off for proper development.

  • Classroom Activities: Gene Switches

    Classroom Activities: Gene Switches

    Activity

    To accompany the lecture series Evolution: Constant Change and Common Threads.

  • Fossils, Genes, and Embryos

    Fossils, Genes, and Embryos

    Lecture

    (58 min 30 sec) The genetic mechanisms by which evolution occurs, and an overview of the evidence for evolutionary theory.

  • Selection in Action

    Selection in Action

    Lecture

    (58 min 29 sec) Comparing the artificial selection of dogs and corn with the natural selection of the stickleback fish.

  • Pitx1 Expression

    Pitx1 Expression

    Animation

    (55 sec) In the stickleback fish, pelvic-fin reduction resulted from changes in the regulatory switch elements of the Pitx1 gene. In the marine ancestor, the Pitx1 gene is activated in the pelvic-fin region during development to generate the fin. In the pelvic-reduced stickleback, the regulatory switch that normally turns on the Pitx1 gene is either missing or non-functional.

  • Balancing the Fat Equation

    Balancing the Fat Equation

    Lecture

    (58 min 20 sec) Dr. Evans reviews how PPARs regulate body weight by controlling whether fat is burned or stored.

  • PPAR-delta Activation in the Muscle Cell

    PPAR-delta Activation in the Muscle Cell

    Animation

    (1 min 45 sec) The PPAR-delta receptor activates certain genes in a muscle cell, resulting in the burning of fat.

  • PPAR-gamma Activation in the Fat Cell

    PPAR-gamma Activation in the Fat Cell

    Animation

    (2 min 49 sec) The PPAR-gamma receptor activates certain genes in a fat cell, resulting in the storage of fat and changes in hormone levels.

  • The Strength of Families: Solving Rett Syndrome

    The Strength of Families: Solving Rett Syndrome

    Lecture

    (58 min 32 sec) 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.

  • X Inactivation

    X Inactivation

    Animation

    (55 sec) This animation shows how the random deactivation of one of the X chromosomes in a pair can lead to a mozaicism in the expression genes. 

  • Sex and Death: Too Much of a Good Thing

    Sex and Death: Too Much of a Good Thing

    Lecture

    (59 min 6 sec) Having too many chromosomes can lead to too much gene expression. Dr. Meyer explains how the gene that controls dosage compensation in C. elegans works.
