A Pre-RNA World? |
The most recent origin of life theory
involves a pre-RNA living molecule. This molecule probably lacked cytosine and ribose.
Because such a molecule no longer exists in life, it is hard to address all the possible
candidates. How can one possibly test an hypothesis phrased as follows: We believe that
some chemical (but we dont know what it was) at one time lived on earth, and this
chemical was capable of self replication. We are confident that one day we will find it,
and prove our hypothesis correct. Next: Assembling the Building Blocks Previous: Prebiotic Ribose
