Mini Review Open Access


The DNA-loops are necessary to recycle the RNA polymerase for the multiple transcription rounds of a gene. The nascent transcript needs to be 3’-end processed: cleaved in a specific position and added a 3´-end poly-(A)-tail to become an mRNA. Under regulated conditions, genes undergo 3´-end RNA processing at different positions. This is called alternative polyadenylation (APA) and, as a consequence, mRNA molecules could have different stabilities and regulated fates. The formation of alternative DNA loops is a key factor in order to get the APA.
