Grabbing a parasite by the tail: U-M team solves 'jumping gene' mystery

Scientists have identified the poly(A) tail as a crucial component in LINE-1 retrotransposition, a process that can cause genetic mutations and diseases. Without the tail, the parasite's jumping ability is significantly impaired, offering new strategies for inhibiting its movement.
