Preventing a genetic uprising in early life

(Babraham Institute) Around half of the human genome is made up of genetic parasites called transposons that can damage our genes, leading to a wide range of genetic illnesses. Normally they are controlled by chemical marks that shut down transposon activity, but there is a time early in life when this isn't possible. Research published in Cell Stem Cell from scientists at the Babraham Institute reveals how molecules called endosiRNAs keep transposons in check.
