According to the RNA world hypothesis, life began when RNA molecules evolved the ability to make more copies of themselves. Now we have discovered an RNA molecule that is almost capable of this – it ...
Two separate laboratory breakthroughs have produced RNA molecules that can build copies of themselves or assemble functional structures without any help from proteins or DNA. These results offer the ...
A 45-nucleotide strand of RNA can now synthesize both its mirror-image complement and a copy of itself, bringing scientists closer than ever to demonstrating how life could have emerged from chemistry ...
On the left are three forms of the same RNA molecule, which is stabilised into a single form (on the right) by mitoxantrone. Ribonucleic acids (RNAs) serve as messengers between DNA and protein ...
While scientists have known for over two decades that all cells use a strategy called RNA interference to regulate gene ...
