Scientists have created a small 45-nucleotide RNA molecule that can synthesize RNA using simple building blocks called trinucleotide triphosphates[7]. This molecule, called QT45, represents a ribozyme polymerase that catalyzes RNA-templated RNA synthesis in mildly alkaline eutectic ice[7]. Research shows that QT45 can synthesize its own complementary strand with an accuracy of 94.1% per nucleotide and also a copy of itself with a yield of approximately 0.2% within 72 days[7]. The discovery of polymerase activity in such a small RNA motif suggests that ribozyme polymerases are more widespread in RNA sequences than previously thought[7]. This research supports the RNA world hypothesis, which posits that life may have arisen approximately 4 billion years ago from RNA molecules capable of self-replication and evolution[1]. Although the current results achieve only partial replication, the researchers say there is no reason why full replication with improved enzyme efficiency cannot be achieved[5].
