    0.325 microliters

    Explanation:

    1 microgram = 1000 nanograms

    DNA sample concentration = 1000 X 0.6 = 600 nanograms / microliters

    We need a total of 50 microliter reactions, and the concentration should be 3.9 nanograms per microliter.

    So, we need total 50 X 3.9 = 195 nanograms in 50 microliters.

    Therefore, it required 195 / 600 = 0.325 microliters of DNA sample to be transferred.
