We report a study of DNA (150 bp fragments) conformations in very low added salt $<0.05$mM, across wide DNA concentration range $0.0015\leq c \leq 8$~mM (bp). We found an intermediate DNA conformation in the region $0.05 < c < 1$~mM, by…

This paper presents a numerical study of the dynamics of DNA double helix breakage under the influence of external forces using the Peyrard-Bishop-Dauxois (PBD) model. The PBD model represents DNA as a chain of nonlinearly coupled…
