There's nothing in biology per se that rules out cell division.

从生物学本身来讲没有事物会胞分裂。

Many have even worse deficits. Moreover, these deficits tend to get worse with time, because when human hair cells die, they're not replaced by cell division.

有些人的听力缺陷更加严重，甚至还会随着时间而进一步恶化，因为当人体的毛胞凋亡后，它们不会通过胞分裂得到补充。

Cell division is an intricate chemical dance that's part individual, part community-driven.

胞分裂，是繁复的化学舞蹈，一部分在胞内生，一部受外界影响。

Shortening with each cell division, they help determine how fast a cell ages.

随着胞分裂的缩短，它们有助于确定胞衰老的速度。

Every cell division carries a risk of creating errors and mutations.

每个胞分裂都有产生错误和突变的风险。

Osteosarcomas often form in the metaphysis where there's a lot of cell division occurring.

骨肉瘤常形成于干骺端，表现为大量胞分裂。

So together there's uncontrolled cell division which can give rise to a tumor.

前述二者共同作用下，会导致胞分裂不受控制，进而可能产生肿瘤。

In FAS, ethanol interferes with cell division and proliferation, cell growth and differentiation and with the migration of mature cells to their final location in the developing embryo which affects the development of various fetal tissues, including the brain.

在FAS中，乙醇会干扰胞分裂、增殖，影响胞生长和分化，并且在胚胎的过程中，妨碍成熟胞迁移到它们最终的部位，这会影响胎儿各种组织的，中包括大脑。

Even after fertilization of the egg and all of the cell divisions it takes to make a person, that epigenetic mark remains – a reminder to keep those maternally-derived copies of the genes turned off.

尽管到胚胎形成前，会生卵子受精、胞分裂等生物学过程，表观遗传的改变会一直保留，使这些母源基因保持沉默。

Typically these are mutations in proto-oncogenes which results in a promotion of cell division, or mutations in tumor suppressor genes which results in a loss of inhibition of cell division.

通常，这些突变是原癌基因突变，会促进胞分裂；或是抑癌基因突变，导致胞分裂的正常抑制被解除。

A genome map showed that Thiomargarita magnifica has lost some genes needed for cell division and has more than the usual number of copies of genes responsible for cell lengthening.

基因图谱显示，华丽硫珠菌已经失去了一些胞分裂所需的基因，拥有了比通常数量更多的负责胞变长的基因副本。

Once we have a growing plant on our hands, Cytokinins stimulate cell division, which allows the plant to build new organs like leaves, stems, and roots.

一旦我们手上有了一棵正在生长的植物，胞分裂素就会刺激胞分裂，从而使植物长出新的器官，比如叶子、茎和根。

It is not possible to be sure, given the length of time involved, that they have undergone no growth and cell division whatsoever.

鉴于所涉及时间的长短，无法肯定它们是否经历过任何生长和胞分裂。

The BCL1 gene encodes the protein cyclin D1, which stimulates cell growth, so once again the translocation results in increased cell division.

BCL1基因编码胞周期蛋白D1，刺激胞生长，所以易位导致胞分裂加速。

Even simple bacteria like E. Coli make about 50 times their body weight in ATP for every cell division.

即使是简单的菌（如大肠杆菌），每次胞分裂所产生的ATP重量也约为体重的50倍。

P16INK4A is part of the control mechanism that brings cell division to a halt when this limit is reached.

P16INK4A 分子是当这一限度达到时令胞分裂终的控制机制的一部分。

There are two types of cell division: Mitosis and Meiosis.

胞分裂有两种类型：有丝分裂和减数分裂。

It inhibits cell division and protein synthesis—both of which are kind of deal breakers for staying alive.

它抑制胞分裂和蛋白质合成，而这两者恰好是生命生存的必需条件。

But when a plant experiences temperature extremes, cell division in the developing fruit can go off track.

但当植物经历极端温度时，正在的果实中的胞分裂可能会偏离轨道。

A) ;;They may shorten the process of cell division.

它们可以缩短胞分裂的过程。
