More RNA from jumping DNA was not linked to shorter life in flies

Experiments in three fruit fly species challenged the idea that jumping DNA concentrated on the Y chromosome helps explain males’ shorter lives.Experiments in three fruit fly species challenged the idea that jumping DNA concentrated on the Y chromosome helps explain males’ shorter lives.
