Mechanisms and evolutionary patterns of mammalian and avian dosage compensation.

abstract：:Transposable elements comprise a huge portion of most animal genomes. Unlike many pathogens, these elements leave a mark of their impact via their insertion into host genomes. With proper teasing, these sequences can relay information about the evolutionary history of transposons and their hosts. In a new publication,...
