Repetitive elements shape embryonic chromatin landscape

(Helmholtz Zentrum München – German Research Center for Environmental Health) Retrotransposons are repetitive elements that form almost half of the mammalian genome. Even though they are so common, they have previously been considered to be fairly insignificant. Together with colleagues from the USA, scientists from the Helmholtz Zentrum München have now shown in Nature Genetics that retrotransposons play an important role in embryonic development.
