junk DNA

基本解釋

Between the genes lay long stretches of “junk DNA,” incoherent, useless, and inert.
之間的基因奠定“垃圾DNA”，語無倫次，沒用，很長(zhǎng)一段惰性。
This particular junk DNA indicates a common ancestry with other species on earth, so it is particularly interesting.
這種廢料DNA說明了，我們和地球上其他物種有著共同的祖先。這也讓這個(gè)“廢物”特別有意思。
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.
其他大多數(shù)動(dòng)物都有這種有用的DNA，不過在我們的進(jìn)化史中，有個(gè)改變讓這種基因失效了——不過還是留下了一點(diǎn)殘余，成了廢料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 Much of the large human genome is comprised of these types of junk DNA that are no longer active.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.

DNA that consists of repeated sequences of nucleotide and has no apparent function DNA
