does the primary structure (seq of AA's) or does secondary structure (a helix, b pleated) determine conformation of DNA

From what I remember (vaguely) it should be the primary structure. Maybe because when you denature a protein, you loose secondary, and tertiary structure but not the primary. Therefore, primary structure posses all the info needed to fold the protein.

I'm not quite sure what you're asking...do you mean to say that proteins (such as histones) help with DNA condensing?

i think that's right...primary determines conformation of DNA

I assume you mean conformation of the protein....

Primary does. It depends on the order of the aa since their interactions will determine how it can arrange itself into a secondary conformation and fold into a tertiary conformation.
