例句：

Their first observation was that , adjusted for age , the telomeres of men and women were the same length .

她们的第一个发现是：与年龄相适应，男人的端粒和女人的端粒长度相同。

The test works by measuring the length of the telomeres and is able to then determine the biological age of a person .

这项检测通过检测染色体端粒的长度，就可以判定一个人的生理年龄。

One set of Mrs. Young's DNA will be sent to Dr. Blackburn's lab , where the length of its telomeres will be measured .

杨女士的一份 DNA 样本会被送往布莱克本的实验室，在那里她的染色体端粒长度会被测量。

Our DNA is carrying chromosomes and at each end of these, a sort of protective caps called telomeres .

我们的 DNA 携带染色体，在每条染色体的末端都有保护性的端粒。

This was the first link between the molecular biology of telomeres and cellular senescence, the aging and death of cells .

这是端粒的细胞生物学首次与细胞的衰老及死亡联系在一起。

The discovery was that the telomeres are actually connected together .

这个发现就是着丝点实际上是连在一起的。

Later , Ms. Blackburn and Ms. Greider discovered the substance in the body that builds telomeres . The scientists named the enzyme telomerase .

后来布莱克本和格雷德发现了人体中用来构筑端粒的物质，并将之命名为端粒酶。

After a cell has grown and divided a few dozen times, the telomeres turn on an alarm system that prevents further division .

当细胞生长并经历几次分裂后，端粒就会开启警报系统防止细胞进一步分裂。

The scientists measured the length of telomeres, the tails on the ends of chromosomes, in sample groups in the Glasgow area .

科学家们测量了格拉斯哥地区样品集合的染色体端粒的长度。

So , it's not certain , but it may be that the beneficial effects of exercise on telomeres really occur via these proteins.

所以，还不确定，但是，运动对端粒的正面影响可能真的是通过这些脂肪发生的。

After about 60 divisions, the telomeres are eroded away to the point that the cell stops dividing .

大约在 60 次分裂之后，调聚物被腐蚀，细胞停止分裂。

Each time a cell replicates itself (as it does before it dies ), the telomeres shorten , like plastic tips fraying on the end of shoelaces .

细胞每复制自己一次（细胞在死亡之前都会如此），其端粒就会缩短，就像鞋带的塑料头会磨损一样。

Why would running or high-level fitness increase the length of the telomeres in the blood ?

为什么跑步或高水准体能可以增加血液中端粒的长度？

Telomeres aren't the only reason we age, likely accounting for 10% or less of the aging process, biologists say .

生物学家称，染色体端粒并非我们衰老的唯一原因。在人类老化过程中，端粒所起的作用至多占 10%。

As people age , telomeres become shorter . But the scientists found that women with higher vitamin D levels tend to have longer telomeres.

由于人们衰老，调聚物变得更短。但是科学家们发现血清高水平维生素 D 的妇女调聚物更长。

The answer lies at the ends of the chromosomes - the telomeres - and in an enzyme that forms them - telomerase.

答案就在染色体的末端 ——端粒和形成端粒的酶 ——端粒酶之中。

Telomeres protect the genes , much like the plastic tips on the ends of shoelaces .

端粒可以保护基因，这种情况恰恰像鞋带末端的塑料帽。

'To a lesser extent, our study also found that unmarried, widowed, or single older adults had shorter telomeres . '

我们的研究某种程度上还发现未婚、丧偶、单身老年人端粒较短。

They targeted the chromosomes that reside within the nuclei of all cells , and specifically telomeres , caps at the tips of chromosomes .

他们的目标是染色体居住在所有细胞的细胞核，特别是在端粒、帽尖的染色体。

Until now , telomeres have been considered to be transcriptionally silent.

直到现在，端粒一直被认为不能作模板参与转录。
