1·Now a telomere is a highly repetitious and genetically meaningless sequence of DNA, what we were calling junk DNA.
端粒是高度重复的，从基因上来说没有意义的 DNA 序列，我们称之为垃圾 DNA。
2·The discoveries had a major impact within the scientific community, and many scientists speculate that telomere shortening could be the reason for ageing.
这些发现在科学界内产生了重大影响，许多科学家推测，端粒缩短可能是人类衰老的原因。
3·In a significant breakthrough, the team successfully identified that a particular gene sequence was associated with differences in telomere length between individuals.
该团队取得了突破性的成功，他们确定了个体身上有个基因序列与端粒的长短密切相关。
4·It gave us great confidence that we identified genetic variants on a pathway we already know is associated with telomere length.
同时也给了我们信心去确定不同遗传变量与端粒长度关系的路径。
5·The new finding is exciting because, he says, "it means that telomere shortening is not inevitable."
他说，这个新发现令人兴奋，因为“它意味着，端粒缩短不是必然的。”
