  1. I would like to clarify some of the confusion. DNA and RNA are very similar, apart from the backbone sugar (RNA has an extra hydroxyl group) and One of the bases, thymidine in DNA, is replaced by Uracil. The hydroxyl group makes it more liable to acid-base hydrolysis In fact, both DNA and RNA can form double helices, and other superstructures, such as hairpins, quadruplexes; triplexes ... A lot is still not well understood, but RNA actually plays a huge role in cells and is much more than just a messenger between DNA and proteins ...
  2. Not sure if we should worry too much about the collision with Andromeda. besides, most likely the collision won't actually cause many stars to collide. Nevertheless, we should watch out during the next billion of years. I think our past history is just as interesting. Earth once had two moons, what do you guys think?
