noncoding DNA

同根派生

Intron A noncoding DNA sequence that occurs between coding sequences (exons) in many eukaryote genes.
內含子：是大多數(shù)真核生物基因中位于編碼序列（外顯子）之間的不編碼的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.
研究兩種果蠅發(fā)現(xiàn)40%25到70%25的非編碼DNA比基因本身進化更慢。
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.
在真核基因組中占有絕大多數(shù)的非編碼DNA似乎沒有明顯的生物學功能，而它們在進化過程中的變化是否受到選擇壓力的限制迄今仍不明了。
DNA fingerprinting can help the police to find the criminals.
DNA指紋術有助於警察發(fā)現(xiàn)罪犯。
One layer is woven throughout the vast “noncoding” sequences of DNA that interrupt and separate genes.
不過在傳統(tǒng)認定的基因之外，至少還有兩層資訊存在。
