Homework Help: Spring Constant of DNA, etc?

  1. Apr 22, 2008 #1
    Consider a segment of a molecule of DNA that is a coil with an overall length of 1.6 μm. If the end of the molecule become singly ionized (one end loosing a single electron and the other end gaining a single electron) the helical molecule acts like a spring and compresses 1.10% of its original length. Determine the effective spring constant of the molecule.

    Consider the force of attraction between the two molecules. This should be enough to move forward.
