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 ...
Although the participation of spliceosomes is almost always required for intron removal, a few types of genes have ...
Each mRNA transcript contains coding regions, known as exons, and noncoding regions, known as introns. They also include sites that act as signals for where splicing should occur, allowing the cell to ...
Human introns have extensively varying lengths. Previously, only U2AF-dependent splicing was known. Researchers from Fujita Health University now show that splicing in a subset of human short introns ...
DNA is the genetic code that provides the biological instructions for every living species, but not every bit of DNA helps the species survive. Some pieces of DNA are more like parasites, along for ...
The origins of introns and their evolutionary role remain unclear. In the November 6 Proceedings of the National Academy of Science, Alexei Fedorov and colleagues describe the use of a computer ...
