移动基因转座子( transposon) Transposon: Transposons are segments of DNa that can move around to different positions in the genome of a single cell. In the process, they may cause mutations or increase(or decrease) the amount of DNa in the genome. These mobile segments of DNa are sometimes called " jumping genes移动基因/转座子（transposon） ◼ Transposon： Transposons are segments of DNA that can move around to different positions in the genome of a single cell.
