1·Now a telomere is a highly repetitious and genetically meaningless sequence of DNA, what we were calling junk DNA.

端粒是高度重复的，从基因上来说没有意义的 DNA 序列，我们称之为垃圾 DNA。

2·Every time the Chromosome divides—every time one cell divides into two—pieces of the ends of the Chromosome, the telomere, get broken off.

当每次染色体分裂时——即当每次一个细胞分裂成两个时——染色体的尾部，也就是端区，就会发生断裂。

3·Anyway, if we examine these ends of these coils of DNA, we will find a sequence of DNA at each end of every human Chromosome, called a telomere.

无论如何，如果我们检查这些螺旋状 DNA 的末端，我们会发现每条人类染色体的末端都有一个被称作“端粒”的 DNA 序列。

4·A telomere is a structure of genetic material.

端粒是一种基因物质的结构。

5·In this way, the telomere ACTS like a biological fuse.

端粒就是以这种方式扮演着生物保险丝的角色。

6·How about habits or routines believed to shorter telomere lengths.

您认为生活习惯或日常活动会缩短端粒长度吗？

7·It would have telomere DNA at the center, and it would have two centromeres.

它的中心部位将有端粒dna，而且会同时含有两个着丝粒。

8·Objective: To study the changes of telomerase activity and telomere length.

目的：探讨肾癌组织端粒酶活性和端粒长度变化。

9·Telomerase is a kind of ERT which causes catalysis and prolong the end of telomere.

端粒酶，是一种催化延长端粒末端的反向转录酶。

10·Genetic factors and environmental stressors can shorten the length of the telomere.

遗传因素和环境压力可以使得端粒的长度缩短。

2·The discoveries had a major impact within the scientific community, and many scientists speculate that telomere shortening could be the reason for ageing.

这些发现在科学界内产生了重大影响，许多科学家推测，端粒缩短可能是人类衰老的原因。

3·In a significant breakthrough, the team successfully identified that a particular gene sequence was associated with differences in telomere length between individuals.

该团队取得了突破性的成功，他们确定了个体身上有个基因序列与端粒的长短密切相关。

4·It gave us great confidence that we identified genetic variants on a pathway we already know is associated with telomere length.

同时也给了我们信心去确定不同遗传变量与端粒长度关系的路径。

5·The new finding is exciting because, he says, it means that telomere shortening is not inevitable.

他说，这个新发现令人兴奋，因为“它意味着，端粒缩短不是必然的。”
