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。708Please respect copyright.ＰＥＮＡＮＡwwzlCnCzNC

而這些染色體、亦即是DNA，將會收藏在細胞裡的細胞核。708Please respect copyright.ＰＥＮＡＮＡHRdnwb5f0H

（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。708Please respect copyright.ＰＥＮＡＮＡDQBBJTrKHl

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。708Please respect copyright.ＰＥＮＡＮＡRySUNx688M

（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)。708Please respect copyright.ＰＥＮＡＮＡLdc53CFYOE

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。708Please respect copyright.ＰＥＮＡＮＡf6vu6IYDAY

（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。708Please respect copyright.ＰＥＮＡＮＡfY7HrJPKKY

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。708Please respect copyright.ＰＥＮＡＮＡknihZ3qvph
708Please respect copyright.ＰＥＮＡＮＡuGDbqRhftZ
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。708Please respect copyright.ＰＥＮＡＮＡQgLRJ3GF4v
