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。
Junk DNA may serve other, unknown purposes.
垃圾dna或许起其它作用，未知名的意图。
Between the genes lay long stretches of "junk DNA," incoherent, useless, and inert.
之间的基因奠定“垃圾dna”，语无伦次，没用，很长一段惰性。
The researchers uncovered the process by which this' junk DNA 'is made active, promoting cancer growth.
研究者提示了该“垃圾dna”被激活后促进肿瘤生长的过程。
There are many hypotheses, none conclusively established, for how junk DNA arose and why it persists in the genome.
有很多假使，最后没有一个被确定，如垃圾DNA怎样激活以及为什么存在于基因组中。
Until now, many biologists have regarded the majority of the genome as "junk DNA" carried from generation to generation but with no biological function.
到目前为止，许多生物学家已将多数基因组，视为代代相传、却没有生物功能的“垃圾DNA”。
Most other animals have this functioning DNA but at some point in our history, a mutation disbled the gene - whilst leaving behind its remnants as junk DNA.
其他大多数动物都有这种有用的DNA，不过在我们的进化史中，有个改变让这种基因失效了——不过还是留下了一点残余，成了废料DNA。
What if the "junk" in our DNA is actually as important as our genes?
假设我们DNA中的“垃圾”实际上同基因一样重要，又会如何？
Could the rest of our DNA really just be junk?
难道我们真的只是休息的DNA是垃圾？
Moreover, the conservation of some "junk" DNA over many millions of years of evolution may imply an essential function.
而且，某些保持了上千万年进化的“垃圾”DNA也意味着一个基本的功能。
Now we are finally pinning down how much differences in non-coding DNA - stretches of the molecule that don't produce proteins and used to be considered "junk" - shape who we are.
现在，我们终于开始着手确定非编码DNA(不产生蛋白质的分子片段，习惯上被认为是“垃圾”)的差异性对人类的影响水平。
The idea that transposable elements (TEs) are mainly 'selfish' or 'junk' DNA with little importance for host evolution has challenged.
转座因子主要是一些“自在”或“无功能”的DNA，其对宿主进化无关紧要的观点受到了质疑。
