A sound result : Calculations have demonstrated a strong influence of acoustic modes on the conductance of double‐stranded DNA (transmission spectrum of a duplex in its ideal B‐DNA conformation is shown in red, that with deformations along DNA acoustic modes in green). The observed temperature independence of the conductivity at and above room temperature arises from a high overall population of such modes above the Debye temperature.
