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 ...

A new study points to introners, one of several proposed mechanisms for the creation of introns, as an explanation for the origins of most introns across species. One of the most long-standing, ...

A novel type of “jumping gene” may explain why the genomes of complex cells aren’t all equally stuffed with noncoding sequences. All animals, plants, fungi and protists — which collectively make up ...
