A commencing and critical step in miRNA biogenesis involves processing of pri-miRNAs in the nucleus by Microprocessor. An important, but not completely understood, question is how Drosha, the catalytic subunit of Microprocessor, binds pri-miRNAs and correctly specifies cleavage sites. Here we report the cryoelectron microscopy structures of the Drosha-DGCR8 complex with and without a pri-miRNA. The RNA-bound structure provides direct visualization of the tertiary structure of pri-miRNA and shows that a helix hairpin in the
