RNA strand that nearly self-replicates could unlock life’s origin

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 ...

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 ...

The “Quite Tiny” RNA Molecule That Could Answer the Question of the Origin of Life

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

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, ...

Could the discovery of a tiny RNA molecule explain the origins of life?

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 ...

DeepChopper model improves RNA sequencing research by mitigating chimera artifacts

Scientists in the laboratory of Rendong Yang, Ph.D., associate professor of Urology, have developed a new large language model that can interpret transcriptomic data in cancer cell lines more ...

Cas13’s Intrinsic Targeting of Host RNA Limits Its Utility

Cas13 is capable of intrinsically targeting host RNA in mammalian cells through mechanisms that were not previously understood. Through transcript-specific mechanisms that are independent of the ...

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 ...

Odd RNA Caps Reveal a New Kind of Gene Transcription

Scientists have found a new process that happens when an active gene is transcribed from DNA into messenger RNA.. | Cell And ...
