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 ...
Shown is the splicing pathway. The pre-messenger RNA (pre-mRNA) has exons (blue) and introns (pink). The spliceosome (not shown) was known to catalyze two chemical reactions (black arrows) in a ...
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 ...
