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。
Now a telomere is a highly repetitious and genetically meaningless sequence of DNA, what we were calling junk DNA.
假设我们DNA中的“垃圾”实际上同基因一样重要，又会如何？
What if the "junk" in our DNA is actually as important as our genes?
之间的基因奠定“垃圾dna”，语无伦次，没用，很长一段惰性。
Between the genes lay long stretches of "junk DNA," incoherent, useless, and inert.
另一组人学习能够导致肥胖的基因和环境因素，例如家族历史和垃圾食品的促销。
Another group learned about the genetic and environmental factors that can contribute to obesity, such as family history and junk food marketing.
大骨架、垃圾食品、基因和糟糕的遗传——导致发胖的原因数不胜数。
Big bones, junk foods, genes or poor parenting-there are plenty of directions in which to point a chubby finger.
大骨头、垃圾食品、基因或贫穷的家庭——有很多直接的原因指向了这个胖乎乎的指状物。

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”。
Until now, many biologists have regarded the majority of the genome as "junk DNA" carried from generation to generation but with no biological function.
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。
There are many hypotheses, none conclusively established, for how junk DNA arose and why it persists in the genome.
