Zinc is an essential component of all kinds of cellular processes, like DNA replication and cell division.

锌是所有细胞进程的必成分，比如说 DNA 的复和细胞分裂。

Unfortunately, this includes DNA repair genes, so by having them silenced, errors during DNA replication don’t get fixed.

不的是，DNA修复基因也可能被沉默，那么DNA复过程中的错误将不能被修复。

Now, these studies need replication on a larger scale, but they show the promise of these memory-destroying treatments for PTSD.

这些研究大规模的重复实验，但它们显示了这些破坏记忆的疗法在治疗创伤后应激障碍方面有相当可观的前景。

Cells have small tubes that assemble to help with cell division and DNA replication, then break back down.

细胞具有组装在一起的小管以帮助细胞分裂和DNA复，然后分解。

But afterwards, scientists couldn't replicate his results, and since replication is key to proving an idea, that was a problem.

但是在此之后，科学家们无法得到相同的实验结果，然而得到相同的实验结果是证明一个理论的关键，所以它无法被证实。

Well, of course it's a replication of B.

这里当然就是重复的B。

The expanded CAG repeats also affect DNA replication itself.

扩展的CAG重复序列也会影响DNA复本身。

The expanded CAG repeats not only affect the huntingtin protein - they affect DNA replication itself.

多余的CAG序列不仅影响huntingtin蛋白，也影响了DNA本身的复。

That prevents the cell from completing its replication, leading to its death.

这阻止了细胞完成其复，其死亡。

But by developing ways to block HIV replication, we can stop the spread of HIV itself.

但是通过发明阻断艾滋病毒自我复的方法，我们可以阻断其传播。

The replication of the viruses then will take place before exiting the host cell by outward budding of the host’s plasma membrane.

病毒的复在胞质中发生，随后通过出芽离开宿主细胞。

It wasn't until some Southern towns noticed the replication that small alterations were made, including adding slouched Confederate caps.

直到一些南方城镇注意到这一重复，他们才做了一些小小的改动，包括添加了无精打采的邦联帽。

By the time a man reaches 50, the cells that create his sperm have gone through over 800 rounds of division and replication.

To survive and reproduce, they must move through three stages: contact with a susceptible host, infection and replication, and transmission to other individuals.

为了生存和繁殖，它们必须经历三个阶段：与易感宿主接触、感染和复、以及传递给其他人。

Alright, as a quick recap, viruses are a unique group of infectious agents with the simple, acellular organization and a distinct pattern of replication.

得！快速回顾一下：病毒是一种独一无二的传染因子；这类非细胞生物结构简单、复模式独特。

PCR is based on DNA replication, a process that our cells normally use to duplicate their genetic material before dividing in two identical daughter cells.

PCR以DNA复为基础；DNA复是我们的细胞通常在分裂成两个相同的子细胞之前复其遗传物质的过程。
