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 ...

Our genome contains the genes that code for the proteins that carry out most biological functions, as well as a lot of other sequence. Some of that other sequence serves various regulatory roles, and ...

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 ...

Researchers confirm that the established pre-mRNA splicing mechanism that appears in textbooks cannot work in a subset of human short introns: A novel SAP30BP–RBM17 complex-dependent splicing has been ...

Group II introns comprise the majority of noncoding DNA in many plant chloroplast genomes and include the commonly sequenced regions trnK/matK, the rps16 intron, and the rpl16 intron. As demand ...

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 ...

In the genome, genes that code for protein are often divided into sections called exons, which are separated by spacers called introns. When a region of DNA is transcribed into messenger RNA (mRNA) or ...

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 ...

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 ...
