    Our genetic blueprint contains numerous entities known as transposons, which have the ability to move from place to place on the chromosomes within a cell. An astounding 50% of human DNA comprises both active transposon elements and the decaying remains of former transposons. Every time a plant or animal cell prepares to divide, the chromosome regions richest in transposon-derived sequences are among the last to duplicate. New research provides potential insight into both these enigmas.
