Crystallized piwi domains contain the site where argonaute proteins bind to the guide strand of the central protein complex involved in this procedure.
On ongoing debate about this processes hinges on its precision when experimenters use controls that fall short of the "rescue control." One step in this process involves cleavage by a 70-nucleotide stem-loop structure containing the enzyme Drosha and the protein Pasha, while CRISPR is sometimes considered a prokaryotic analogue of it. Early experiments with this pathway included the discovery of (*) "quelling" in Neurospora crassa and Jorgensen's experiments with the pigmentation of petunias. Crystallized piwi domains contain the site where argonaute proteins bind to the guide strand of the central protein complex involved in this procedure. This pathway begins when the enzyme dicer cleaves the double stranded variety of a certain molecule and adds it to the RISC complex. Fire and Mello won the 2006 Nobel Prize for experimenting with this process in C. elegans. For 10 points, name this process of gene silencing that uses siRNA and miRNA to bind to mRNA and impact its action.
