One of the themes I have persisted with in these posts is that in chemistry, thinking about theory is either dead or in terminal decline. Prove me wrong!
 
In my last post, I offered a challenge to readers, specifically, can you provide answers to:
1.     Why did nature choose ribose for nucleic acids?
2.     How did homochirality arise?
So far, I have no guesses/inspired answers. Come on! Assuming someone is actually reading these posts, either they don't care or it is too difficult. Now, surely you are not going to concede that I can work out more than you can? So, is anyone going to try?
 
My first answer next week.
