The essential cis- and trans-acting elements required for RNA splicing have been defined, however, the detailed molecular mechanisms underlying intron–exon recognition are still unclear. Here we ...

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 ...

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 ...
