    The researchers created a ribozyme that could make a complementary
    strand and then a copy of itself from the complementary strand.

    The problem seems to be that you need two molecules of the ribozyme to
    do this. They have to figure out how two such ribozyme sequences were initially created. It is only 45 nucleotides long, so they think that
    such a simple sequence motif means that polymerase activity is fairly
    common in RNA sequence space and that many other such replicators could evolve.
