noncoding DNA

同根派生

Intron A noncoding DNA sequence that occurs between coding sequences (exons) in many eukaryote genes.
内含子：是大多数真核生物基因中位于编码序列（外显子）之间的不编码的DNA序列。
A study of two species of fruit flies found that 40% to 70% of noncoding DNA evolves more slowly than the genes themselves.
研究两种果蝇发现40%25到70%25的非编码DNA比基因本身进化更慢。
An overwhelming percentage of noncoding DNA in eukaryotes serves no known biological role and whether most of them evolve without selection constraints remains in debates.
在真核基因组中占有绝大多数的非编码DNA似乎没有明显的生物学功能，而它们在进化过程中的变化是否受到选择压力的限制迄今仍不明了。
DNA fingerprinting can help the police to find the criminals.
DNA指纹术有助於警察发现罪犯。
One layer is woven throughout the vast “noncoding” sequences of DNA that interrupt and separate genes.
不过在传统认定的基因之外，至少还有两层资讯存在。
