Malicious jumping genes meet their match: Study reveals cell's adaptive piRNA defenses

Adverse genetic mutations can cause harm and are due to various circumstances. "Jumping genes" are one cause of mutations, but cells try and combat them with a specialized RNA called piRNA. For the first time, researchers from the University of Tokyo and their collaborators have identified how the sites responsible for piRNA production evolve effective behaviors against jumping genes. This research could lead to downstream diagnostic or therapeutic applications.
