Nuclear processing by Drosha Microprocessor complex. The primary-microRNA (pri-miRNA) is recognized by the Microprocessor complex (Drosha:DGCR8) and both strands of the pri-miRNA are cleaved by Drosha near the free 5' and 3' ends of the pri-miRNA, that is, at the ends distal from the internal loop. The product is a double-stranded RNA having 2 nucleotides protruding at the 3' end and having an internal loop.
