That kind of pressure and heat would destroy the necessary chemical bonds for all of the other things that go into a living cell.

Would it? Think ~ the pressure simply creates a condition where water molecules take the form of a double-helix. They, themselves, the water molecules, necessary for life BTW, exist.

By crushing the existence out of all the other molecules of whatever kind in the vicinity, you have your source for other materials to form appropriate base pairs.

How they would get into the new water molecule double-helix matrix I have no idea.

It is possible fully functional DNA or RNA springs to "life" fully formed and ready to roll ~
