Dear Kalyanashis,

VMD can perform DNA and RNA mutations. You can use "mutate" command ( from psfgen to
mutate either protein or nucleic residues.

I would like to also mentioned that there is a new VMD plugin that
streamlines MD simulation preparation, execution and analysis named QwikMD.
If you would like try I would be glad to give you more instructions how to
get it.
