我們身體細胞的DNA，會經過不同蛋白質的幫助下接疊以及壓縮，成為名為染色體(Chromosome)的結構。490Please respect copyright.ＰＥＮＡＮＡllvEF5GK6a

而這些染色體、亦即是DNA，將會收藏在細胞裡的細胞核。490Please respect copyright.ＰＥＮＡＮＡoagzfRzEKc

（圖2）細胞進行自我複製時，將會複製自己的DNA，並會暫時性將細胞核的外膜消除。490Please respect copyright.ＰＥＮＡＮＡkIazioqgnA

被複製的DNA會排在中間，然後經由線狀結構(綠色)往左右兩方邁進。490Please respect copyright.ＰＥＮＡＮＡOC3YPAm1n8

（圖3）往左右兩方邁進的染色體，有時候會出現跑得較為慢的染色體(圖中藍色箭嘴)。490Please respect copyright.ＰＥＮＡＮＡvq3EtOZhOA

落後於人的染色體，最終有機會無法加入正常大隊，並自立一閣形成名為micronucleus的結構。490Please respect copyright.ＰＥＮＡＮＡj4i65IGChv

（圖4）這些名為micronucleus的結構，基於其外膜的發展並不完善，因此非常容易會出現損壞的情況。490Please respect copyright.ＰＥＮＡＮＡwSqaFatE1y

當外膜受到損毀，裡頭的DNA有極大機會遭受襲擊，因此出現變異的情況。490Please respect copyright.ＰＥＮＡＮＡ9eT8apU4k9
490Please respect copyright.ＰＥＮＡＮＡiRoR297pIy
而這些變異的DNA，往往就是讓正常細胞發展成為癌細胞的契機。490Please respect copyright.ＰＥＮＡＮＡVUUv2MouKq
