Is there some way that I can link objects to a path so that I can change the path and have the objects follow it? I've made an SVG to demonstrate what I mean (in this example, I had to move the objects manually to match the path. This would be a very tedious method for my actual intention.

My actual intention is to construct a PCR (OE-PCR) illustration for Wikipedia. If you take a look at this, made by someone else:

you see the DNA strands that I have in mind. I want to be able to bend them easily as though they were a single contiguous path, without having to re-adjust each object.
