We observed signatures of a phase transition in the double-stranded DNA fragment of known length and sequences using a non-invasive semiconductor-electrolyte interface technique and statistical physics methods. Observations revealed a coherence peak in the electromotive force and a significant decline in calculated dynamic entropy at a critical temperature and pH. This behavior may arise from the dynamic interaction of proton (H+) pairs with opposite momentum and spin, carrying a charge q=2+ under critical conditions.
