CTRL+X and CTRL+V in DNA: Jumping genes caught mid-jump
Transposons, known as jumping genes, can 'cut themselves out' from the DNA, and then paste into its another, often precisely selected place. Scientists view them as the future of genome editing. Polish researchers have recently completed a difficult task: they described the key protein related to the action of the transposon when this is 'getting ready to jump'.
