  The thermal conductivity of B-form double-stranded DNA (dsDNA) of the
Drew-Dickerson sequence d(CGCGAATTCGCG) is computed using classical Molecular
Dynamics (MD) simulations. In contrast to previous studies, which focus on a
simplified 1D model or a coarse-grained model of DNA to improve simulation
times, full atomistic simulations are employed to understand the thermal
conduction in B-DNA. Thermal conductivity at different temperatures from 100 to
400 K are investigated using the Einstein Green-Kubo equilibrium and
M\"uller-Plathe non-equilibrium formalisms. The thermal conductivity of B-DNA
at room temperature is found to be 1.5 W/m$\cdot$K in equilibrium and 1.225
W/m$\cdot$K in non-equilibrium approach. In addition, the denaturation regime
of B-DNA is obtained from the variation of thermal conductivity with
temperature. It is in agreement with previous works using Peyrard-Bishop
Dauxois (PBD) model at a temperature of around 350 K. The quantum heat capacity
($C_{vq}$) has given the additional clues regarding the Debye and denaturation
temperature of 12-bp B-DNA.
