Researchers at University College London used synthetic RNA building blocks known as trinucleotides.

These don’t appear in modern life, but offer a simpler structure that might have existed billions of years ago .

In the experiment, the RNA was exposed to heat, acid, and freezing conditions in water.

These temperature cycles helped the strands avoid sticking back together, which allowed the RNA to continue growing.

Eventually, the strands grew long enough to start behaving more like biological molecules.

Although the researchers have so far only managed to replicate about 17% of an RNA strand, they believe full replication is possible.
