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 ...
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, ...
