N DNA that consists of repeated sequences of nucleotide and has no apparent function 垃圾DNA
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。
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”。
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。
