DNA and its counterions: a molecular dynamics study

The behaviour of mobile counterions, Na(+) and K(+), was analysed around a B-DNA double helix with the sequence CCATGCGCTGAC in aqueous solution during two 50 ns long molecular dynamics trajectories. The movement of both monovalent ions remains diffusive in the presence of DNA. Ions sample the compl...
