One of the most long-standing, fundamental mysteries of biology surrounds the poorly understood origins of introns. Introns are segments of noncoding DNA that must be removed from the genetic code ...

The sequences of nonsense DNA that interrupt genes could be far more important to the evolution of genomes than previously thought, according to researchers. Their study of the model organism Daphnia ...

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 ...

Pre-mRNA splicing in a subset of human short introns is governed by a distinct mechanism involving a new splicing factor, new research finds. The interrupted non-coding regions in pre-mRNAs, termed ...

Mysterious gene structures called introns that help make complex organisms possible are descended from DNA parasites that infested bacteria billions of years ago, according to a new study. Researchers ...

Researchers have long puzzled over why many eukaryotic protein-coding genes are interspersed with segments of noncoding DNA that have no obvious biological function. These so-called introns are ...

Alternative splicing (AS) is a major contributor to transcriptome and proteome diversity. Evolutionary studies help to address questions that are fundamental to understanding this important process.

Pre-mRNA splicing in a subset of human short introns is governed by a distinct mechanism involving a new splicing factor Protein-coding genes carry the blueprint for protein production. In higher ...

The interrupted non-coding regions in pre-mRNAs, termed “introns,” are excised by “splicing” to generate mature coding mRNAs that are translated into proteins. As human pre-mRNA introns vary in length ...
