[Chimera-users] Adding residue to two sides of DNA

[Elaine Meng]

Dear Mahdi,
Sorry, Chimera only includes changing the type of a nucleotide that is already in the DNA structure (command "swapna"),
<http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/swapna.html>

... or building a whole double helix from scratch, that is, without any starting structure (menu: Tools… Structure Editing… Build Structure, section: Start Structure, option: helical DNA/RNA)
<http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/editing/editing.html#start>

I don't have much experience building DNA.  Here are a couple web-servers, but I think they also only build entire structures from scratch:

<http://w3dna.rutgers.edu/index.php/rebuild>
