This gives the cells more time to repair themselves.

细胞得到了更多自我修复的时间。

I've tried his cell a few times, no answer.

我给他打了很多次电话，都没人接。

Each time cells divide, there is a chance of a mutation and the possibility of tumor formation.

细胞每分裂一次，就有突变和形成肿瘤的机会。

I lose brain cells every time I hear you speak.

每次听到你说话我都会失去脑细胞。

Most of the time, cells can detect mutations or DNA damage and either fix them or self destruct.

大多数时候， 细胞可以检测到突变或 DNA 损伤，并修复它们或自我毁灭。

Each time cells divide there's a chance that a genetic mutation will occur and a mutation can lead to tumor formation.

每次细胞分裂都有可能发生基因突变，而突变就可能会导致肿瘤的形成。

At the time, cell biologist George Palade guessed that small sacs filled with liquid called " vesicles" had something to do with it.

当时，细胞生物学家乔治·帕拉德猜测，被称为 " 囊泡 " 的充满液体的小液囊与此有关。

At the time, cell biologist George Palade guessed that small sacs filled with liquid called " vesicles" had something to do with it.

霍尔：当时，细胞生物学家乔治·帕拉德 (George Palade) 猜测，充满液体的称为“囊泡”的小囊与此有关。

I'm Paul Nurse, and I've spent much of my working life thinking about DNA, in particular how it's copied and distributed inside cells every time they divide.

我是保罗·纳斯，我的大部分工作时间都在研究 DNA，尤其是每次细胞分裂时它都如何在细胞内复制和分布。

Each time cells divide there is a chance of a mutation and the possibility of tumor formation, and this means that with more ovulatory cycles, there's increased risk of tumor formation.

每一次细胞分裂时都有细胞突变的可能，同时也增加了肿瘤形成的可能性，而这也意味着排卵期的循环提高了癌变的风险。

Of course, at this point, O2 is poisonous to most organisms, but over time, cells evolve to tolerate it, and because metabolic reactions using O2 were more efficient, cells could grow larger.

当然，在这一点上，氧气对大多数生物体都是有毒的，但随着时间的推移，细胞进化出了对氧气的耐受能力，而且由于使用氧气的代谢反应更有效，细胞可以生长得更大。
