During RNA maturation, the group I intron promotes two sequential phosphorotransfer reactions resulting in exon ligation and intron release. Here, we report the crystal structure of the intron in ...

What if you could flip a genetic switch to silence a gene, then turn it back on with a simple drug? For researchers, gene-switch tools offer that kind of control—and a new system called Cyclone may ...

This is a preview. Log in through your library . Abstract RNA is commonly believed to undergo a number of sequential folding steps before reaching its functional fold, i.e., the global minimum in the ...

Introns and exons are nucleotide sequences within a gene. Introns are removed by RNA splicing as RNA matures, meaning that they are not expressed in the final messenger RNA (mRNA) product, while exons ...
