    Got Lactase? Blood Glucose Data Analysis

    Activities

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

  • Lactose Digestion in Infants

    Lactose Digestion in Infants

    Animations

    (53 sec) The lactase enzyme is produced in the small intestine of infants. It digests lactose by breaking it into glucose and galactose.

  • Diet and the Evolution of Salivary Amylase

    Diet and the Evolution of Salivary Amylase

    Activities

    Students explore the effects of different diets on the evolution of an enzyme that breaks down starch. Also available in Spanish.

  • Biochemistry and Cell Signaling Pathway of the Mc1r Gene

    Biochemistry and Cell Signaling Pathway of the Mc1r Gene

    Activities

    An advanced lesson that requires students to analyze partial DNA sequences of the Mc1r gene and identify the effects of mutations on the MC1R protein pathway.

  • The Chemical Structure of DNA

    The Chemical Structure of DNA

    Animations

    (2 min 44 sec) DNA's chemical properties can be harnessed for a variety of biotechnology applications.

  • Polymerase chain reaction (PCR)

    Polymerase chain reaction (PCR)

    Animations

    (54 sec) PCR is a standard laboratory technique that allows amplification of specific segments of DNA based on complementarity.

  • Signal molecules trigger transcription factors

    Signal molecules trigger transcription factors

    Animations

    (2 min 4 sec) Varying concentrations of a signaling molecule activate different transcription factors and determine cell fate.

  • AZT blocks reverse transcriptase

    AZT blocks reverse transcriptase

    Animations

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

  • Visualizing Gene-Expression Patterns

    Click & Learn

    Learn about the different ways scientists are able to detect when genes are being expressed in various tissues.

  • Watson constructing base pair models

    Watson constructing base pair models

    Clips

    (1 min 42 sec) During the process of trying to elucidate the structure of DNA, Jim Watson made some cardboard models to try to understand how DNA nucleotides are paired. It helped him visualize how hydrogen atoms of paired nucleotides interact with each other to form a symmetrical structure that fits the double helix model.

  • Polymerase chain reaction

    Polymerase chain reaction

    Animations

    (1 min 28 sec) Polymerase chain reaction, or PCR, is a technique for making many copies of a specific DNA sequence. DNA is repeatedly heated and cooled in the presence of primers that bracket the desired sequence and of the enzyme Tac polymerase. In as few as 30 cycles, a billion copies of the target sequence can be made.
