Ovary Changes With Jumping Gene Invasion

Caption

The team found that reproductive stem cells use a novel adaptive response to quickly tame the invading jumping gene elements by activating the so-called DNA damage checkpoint. That is a pause in the cell cycle, which allows for DNA repair. The images depict ovary morphology changes over time after jumping gene invasion, the DNA damage checkpoint pause, and the repair process that ensues after day four.
