Exons are coding sections of an RNA transcript, or the DNA encoding it, that are translated into protein. Exons can be separated by intervening sections of DNA that do not code for proteins, known as ...

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 ...

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 ...

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 ...

This process enables a single gene to produce multiple proteins; over evolutionary timescales, splicing can also change the size and content of genes and proteins, when different exons become included ...

The eukaryotic spliceosome is a multi-megadalton ribonucleoprotein (RNP) complex found in eukaryotic nuclei that catalyzes the removal of introns (non-coding regions) from pre-mRNA and splices exons ...

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, ...

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 ...
