- - There's another enzyme involved called telomerase, and it keeps rebuilding, like, it doesn't let the telomere ever shrink, so it... - It rebuilds the telomere? - Right, exactly.
- 另有一種名叫端粒酶的酵素，它會不斷再生，不讓端粒變短，所以... - 它能重建端粒？ -沒錯。
- Some people would say maybe, "I want my telomerase to be higher for longer." Would that help? I mean, would that keep us younger?
有些人會說：「我想要讓我的端粒更長。」那有幫助嗎？那會讓我們常保年輕嗎？

- It's believed that psychological intervention, particularly decreasing stress, has a direct effect on the enzyme telomerase, which has been shown to counteract shortening by adding DNA to the shrinking telomeres.
據信，心理反應的介入，尤其是壓力的減輕，對於端粒酶有直接影響，研究證實它會在萎縮端粒中加入 DNA，以對抗端粒的縮短。

端粒酶的功能
- The addition of telomeric repeat sequences by an enzyme complex referred to as telomerase assures that this shortening does not occur. Telomerase is a unique and interesting enzyme because, in addition to having DNA polymerase activity, it also contains an RNA sequence that provides a template for the synthesis of telomeric repeat DNA.
被稱為端粒酶的酶複合物會添加端粒重複序列，以確保這種縮短不會發生。 端粒酶是一種獨特而有趣的酶，因為它除了具有 DNA 聚合酶活性外，還含有一種 RNA 序列，可為端粒重複 DNA 的合成提供模板。

- called telomerase. This molecule is mostly found in an important type of cell called a stem cell.
稱為端粒酶。這種分子主要存在於一種叫做幹細胞的重要類型的細胞中。
- Stem cells need to produce new cells throughout life and telomerase lets them keep their telomeres
幹細胞在整個生命過程中需要產生新的細胞，而端粒酶讓它們保持其端粒。
