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

因此， 正是由于它们丰富的端粒酶，我们的池塘浮渣生会变老。

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

但是当我们对进行化学分析时， 我们发现了一非常有趣的东西，它们中的一种化学质， 一种叫做端粒酶的酶。

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

但是当我们用化学方法分析这时，我们发现了一种非常有趣的化学质，一种叫做端粒酶的酶。

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酶让任何保持活力， 并使其永远自我繁殖。

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的端粒酶时，它们的端粒就会流失并死亡。

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.

当染色体末端的端粒脱落时，这种化学质， 这种端粒酶可以重建它，帮助重新组装保护性 DNA，即染色体丢失的端粒。

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，由于这化学质，端粒酶可以防止染色体末端的端粒变短，因此我们可能拥有几乎朽的神经和朽的皮肤。

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的神经和永生的皮肤或其他，因为这种化学质，端粒酶，可以防止染色体末端的端粒变短。
