So it was thanks to their plentiful telomerase that our pond scum critters never got old.

因此， 正是由于它们丰富端粒，我们池塘浮渣生物才不会变老。

But when we analyze the cells chemically we find something very interesting, a chemical in them, an enzyme called telomerase.

但是当我们对细胞学分析时， 我们发现了一些非常有趣东西，它们中一种学物质， 一种叫做端粒。

But when we analyze these cells chemically, we find something very interesting, a chemical in them, an enzyme called telomerase.

但是当我们用学方法分析这些细胞时，我们发现了一种非常有趣学物质，一种叫做端粒。

And when we removed our pond scum's telomerase, their telomeres ran down and they died.

当我们去除池塘浮渣端粒时，它们端粒就会流失并死亡。

Someday we may be able to take any cell and keep it alive functioning and reproducing itself essentially forever through the use of telomerase.

有一天，我们也许能够利用端粒让任何细胞保持活力， 并使其永远自我繁殖。

As bits of the telomere break off from the end of the Chromosome, this chemical, this telomerase can rebuild it, can help reassemble the protective DNA, the telomere that the Chromosome has lost.

当染色体末端端粒脱落时，这种学物质， 这种端粒可以重建它，帮助重新组装保护性 DNA，即染色体丢失端粒。

And in the future we may have virtually immortal nerve cells and immortal skin cells or whatever, because this chemical, telomerase, can keep the telomeres on the ends of Chromosomes from getting any shorter.

将来，我们可能会拥有几乎永生神经细胞和永生皮肤细胞或其他细胞，因为这种学物质，端粒，可以防止染色体末端端粒变短。

And in the future we may have virtually immortal nerve cells and immortal skin cells of whatever because of these chemical, telomerase can keep the telomere on the ends of Chromosomes from getting any shorter.

并且在未来，由于这些学物质，端粒可以防止染色体末端端粒变短，因此我们可能拥有几乎不朽神经细胞和不朽皮肤细胞。
