也称间接分裂”。多细胞生物细胞分裂的主要方式。细胞分裂时，染色体复制成两份，使产生的两个子细胞都有与母细胞相同数目的染色体。整个分裂过程分为前期、中期、后期和末期。

• The cell prepares for meiosis just as it does for mitosis. But as the DNA condenses, each chromosome finds its homologous counterpart.

  细胞减数分裂的准备同有丝分裂一样。但是，随着DNA的浓缩，每个染色体都会与其同源染色体配对。

• For over a century, scientists have strived to understand the mechanisms that govern the accurate segregation of chromosomes during mitosis.

  一个多世纪以来，科学家一直努力了解管理机制，在有丝分裂染色体的精确分离。

• Such a clearing mechanism that operates along mitotic chromosomes might require proteins that are implicated in chromosome segregation.

  这种信息的机制，运作以及有丝分裂染色体可能需要的蛋白质，有牵连的染色体分离。

• there is no cytologic atypia in this case . rare cases may show mild cytologic atypia . increased mitotic is usually not seen.

  本例未见到细胞异型性。极少的病例中可显示轻度的细胞异型性。增加的有丝分裂像通常见不到。

• Ellenberg and his colleagues more than doubled the number of genes that are known to be involved in mitosis, a type of cell division.

  Ellenberg和他的同事们提高了参与有丝分裂（细胞分裂的一种类型）基因数量两倍以上。

• Alternatively, like allopolyploids, they may arise by the nondisjunction of chromatids during the mitotic division of a zygote.

  与异源多倍体相似的是，它们也是在有丝分裂中合子的染色单体不分离形成的。

• A. During the heart stage mitosis occurs; and during the torpedo stage cytokinesis occurs.

  在心的过程中会出现阶段有丝分裂；并在鱼雷阶段细胞浆移动发生。

• Microtubules are shown in green, actin is in red and mitotic chromosomes are colored blue.

  绿色的是微丝，红色为肌动蛋白，正在有丝分裂的染色体为蓝色，正在向两极运动。

• The X chromosome is shown here in a condensed state, as it would appear in a cell that's going through mitosis.

  染色体在这里呈现出浓缩状态，如同他在细胞有丝分裂时呈现的那样。
