GENETICS:
L1 Retrotransposons Shape the Mammalian Genome

Haig H. Kazazian Jr.

What are all of those retrotransposons doing buzzing about in our genome? According to Kazazian, in his Perspective this week, these mobile pieces of DNA are busy reshaping our genome, making it more diverse and enabling us to survive and thrive through the vagaries of evolution. And just how do they do this?...zip to page 1152 to find out.
