How certain proteins contribute to the formation of a class of RNA critical to protecting the genome investigated

You're likely familiar with RNA, the molecule that plays an important role in protein production and gene expression control. Perhaps you're less familiar, however, with PIWI-interacting RNA (piRNA), a special type of RNA that protects the genome from mutations. Now, researchers in Japan have shed light on how these critical molecules are formed by the dynamics of several associated proteins in the germline of the fruit fly, Drosophila melanogaster.
