I'm so new that I'm not even sure where this reply will go. But there was this comment that said I had to make two of something to not get kicked off, so maybe this will help. I'm a chemist that studies biology, so I'll be browsing for a while.

The origin of complicated polymers on the surface of an early ocean would have to include protection against the UV radiation that would have been present at the time. With no oxygen in the atmosphere there would have been high UV breaking down most molecules and polymers that floated unprotected on the surface. Although UV might have also served as a source for synthesis it would also caused breakdown of products. This seems like an excellent dynamic to research for the actual origin of homochiral ribose and polymers of RNA. This might have supplied molecules for the RNA world.
