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, ...

From vaccines and diagnostics to emerging gene-based therapies, RNA molecules are now central to modern medicine. But as ...

Researchers at the MRC Laboratory of Molecular Biology in Cambridge have discovered a ribozyme that is shockingly small, yet ...

tRNA is an important component of the biological synthesis of new proteins, as it carries a specific amino acid that will be incorporated to the protein through the ribosome machinery, as directed by ...

Life may have begun when RNA molecules began to replicate themselves, and now we’ve finally found an RNA molecule that is very close to being able to do this ...

One of the greatest mysteries of our planet is how a soup of lifeless chemicals transformed into the first living cell. There are several competing theories about where this happened, from frozen ...

RNA is one of the bodies most vital molecules, and it comes in a few forms. For example, messenger RNA fills an essential role in gene expression by copying the sequences of active genes, which are ...

Add Yahoo as a preferred source to see more of our stories on Google. A new study uncovers how amino acids could have linked with RNA under early Earth conditions, shedding light on the origin of life ...

Researchers have recently discovered a novel type of RNA known as circular RNAs (circRNAs). These molecules form when covalent bonds link the ends of a molecule of RNA together to form a circle. This ...
