Self-building RNA strand may expose how life on Earth truly began

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 ...

RNA is key to the dark matter of the genome. Scientists are sequencing it to illuminate human health and disease

Although there are striking differences between the cells that make up your eyes, kidneys, brain and toes, the DNA blueprint ...

Tiny, 45 base long RNA can make copies of itself

These random molecules were fed a collection of three-base-long RNAs, each linked to a chemical tag. The idea was that if a molecule is capable of ligating one of these short RNA fragments to itself, ...

UAB researchers uncover protein SRSF1’s uncommon ability to bind and unfold RNA G-quadruplexes

RNA transcription is the genomic process in which a cell produces a duplicate of a gene’s DNA sequence. Present in both DNA and RNA sequences, a G-quadruplex (GQ) is a structure of four guanine bases ...
