junk DNA

基本解释

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。
This particular junk DNA indicates a common ancestry with other species on earth, so it is particularly interesting.
这种废料DNA说明了，我们和地球上其他物种有着共同的祖先。这也让这个“废物”特别有意思。
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。

And of course Wells cites multiple scientists who have used junk DNA as an argument against intelligent design.
FORBES: The Myth ... of the Myth of Junk DNA
They have degenerated into junk DNA. Much of the large human genome is comprised of these types of junk DNA that are no longer active.
FORBES: The Myth ... of the Myth of Junk DNA
Rather, it is selfish or junk DNA, a molecular parasite that, over many generations, has disseminated itself throughout the genome through some sort of transpositional process.
