  The equilibrium structure of a Dinucleosome is studied using an elastic model
that takes into account the force and torque balance conditions. Using the
proper boundary conditions, it is found that the conformational energy of the
problem does not depend on the length of the linker DNA. In addition it is
shown that the two histone octamers are almost perpendicular to each other and
the linker DNA in short lengths is almost straight. These findings could shed
some light on the role of DNA elasticity in the chromatin structure.
