  1. Mode of DNA replication: Meselson-Stahl experiment - Khan …

    The semi-conservative model, in which each strand of DNA serves as a template to make a new, complementary strand, seemed most likely based on DNA's structure. The models were tested …

  2. Semi-conservative replication (video) | Khan Academy

    DNA replication has three possible methods: conservative, dispersive, and semi-conservative. Here, we focus on the Meselson-Stahl experiment, which proved DNA replication is semi …

  3. Mode of DNA replication: Meselson-Stahl experiment

    The semi-conservative model, in which each strand of DNA serves as a template to make a new, complementary strand, seemed most likely based on DNA's structure. The models were tested …

  4. Semi-conservative replication (video) | Khan Academy

    The semi-conservative model ensures genetic continuity by using one parental DNA strand as a template to make a new complementary strand. Each new DNA molecule has one old and one …

  6. DNA structure and replication review (article) | Khan Academy

    DNA replication is semi-conservative. This means that each of the two strands in double-stranded DNA acts as a template to produce two new strands. Replication relies on complementary …

  7. Potential energy and conservative forces - Khan Academy

    Learn how to model the potential energies associated with gravitational and spring force interactions. Explore the special energy properties associated with the work done by …

  8. Conservative forces (video) | Khan Academy

    A conservative force exists when the work done by that force on an object is independent of the object's path. Instead, the work done by a conservative force depends only on the end points …

  9. Gene expression and regulation | AP®︎/College Biology | Khan …

    Examine the semi-conservative model, where each new molecule retains one original strand. Discover how molecular mechanisms achieve both speed and precision to preserve genetic …

  10. DNA replication (article) | Khan Academy

    DNA replication is semi-conservative During DNA replication, the two strands of the DNA double helix are unwound and separated by enzymes. Each strand then serves as a template, or …
