The initiation phase of eukaryotic transcription via RNA polymerase II is considered an assembly and disassembly process.

Question:

The initiation phase of eukaryotic transcription via RNA polymerase II is considered an assembly and disassembly process. Which types of biochemical interactions-hydrogen bonding, ionic bonding, covalent bonding, and/or hydrophobic interactions-would you expect to drive the assembly and disassembly process? How would temperature and salt concentration affect assembly and disassembly?
