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 ...

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 ...

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 ...

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 ...

Scientists have discovered that some tiny segments of RNA thought to be junk instead have a functional role in suppressing ...
