DNA condensation and redissolution: Interaction between overcharged DNA molecules

E.Allahyarov, G.Gompper, H.L\"owen

Overcharged DNA molecules interact via a double-minimum force that produces condensation, redissolution, and an intermediate mesocrystal.

Claims

C1strongest claim

For overcharged DNA molecules, the interaction force shows a double-minimum structure... A DNA-condensation and redissolution transition and a stable mesocrystal with an intermediate lattice constant for high counterion concentration are obtained.

C2weakest assumption

The effective force extracted from two-molecule simulations remains quantitatively valid when many DNA molecules pack together at finite density.

C3one line summary

Simulations reveal a double-minimum DNA-DNA force that drives condensation-redissolution transitions and a stable mesocrystal at high counterion concentration.
