Simulations of nucleic acids and their complexes.

Recent years have seen considerable progress in simulations of nucleic acids. Improvements in force fields, simulation techniques and protocols, and increasing computer power have all contributed to making nanosecond-scale simulations of both DNA and RNA commonplace. The results are already helping to explain how nucleic acids respond to their environment and to their base sequence and to reveal the factors underlying recognition processes by probing biologically important nucleic acid-protein interactions and medically important nucleic acid-drug complexation. This Account summarizes methodological progress and applications of molecular dynamics to nucleic acids over the past few years and tries to identify remaining challenges.
