Molecular dynamic analysis of ion distributions around DNA strand
The charged ions that surround DNA molecules can dramatically affect its conformation, folding and dynamics. This visualization is from a molecular dynamics simulation of a DNA system where the electron density of the surrounding ions was critical to understanding how they might modulate the structure and interactions of the DNA double helix.
