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，们的池塘浮渣生才不会变老。

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

但是当们对细胞进化学分析时， 们发现了些非常有趣的东西，它们中的种化学， 种叫做端的。

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

当们去除池塘浮渣的端时，它们的端就会流失并死亡。

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，由于这些化学，端可以防止染色体末端的端变短，因此们可能拥有几乎不朽的神经细胞和不朽的皮肤细胞。
