junk dna 解釋
無用dna
  • junk : n 1 （肉等的）大塊，厚片。2 （填縫隙用的）舊繩絮。3 〈古語〉（船上用的）腌牛肉。4 〈口語〉零碎廢...
  • dna : 1. deoxyribonucleic acid 【生物化學】去[脫]氧核糖核酸。2. deoxypentose-nucleic acid 去[脫]氧戊糖核酸。
  1. Since known functional sequence comprises less than 2 % of the human genome, it appears that there may be more functional " junk " dna in the human genome than there is known functional sequence

    由於已知的功能性排序由2 %人類基因組組成，這好象在人類基因組內比已知的功能性排序可能有更多功能性「垃圾」 dna 。
  2. Comparative genomics is a promising direction in studying the function of junk dna

    基因比較在研究垃圾dna方面是有希望的方法。
  3. Junk dna may act as a protective buffer against genetic damage and harmful mutations

    垃圾dna也許在抗拒遺傳破壞和有害突變方面扮演著保護緩沖的角色。
  4. Some junk dna could simply be spacer material that allows enzyme complexes to form around functional elements more easily

    某些垃圾dna或許只是允許酶更容易合成形成周圍功能元素的中間材料。
  5. In this way, the junk dna could serve an important function even though the actual sequence information it contains is irrelevant

    以這種方式，垃圾dna就可以起一個重要作用甚至它擁有的實際排序信息是不相關的。
  6. Junk dna might provide a reservoir of sequences from which potentially advantageous new genes can emerge. in this way, it may be an important genetic basis for evolution

    垃圾dna或許提供了一個排序庫，從這個庫里潛在有利新基因能夠顯現。以這個方式，它也許是一個進化的重要遺傳元素。
  7. On a theoretical note, it is often observed that the presence of high proportions of truly nonfunctional " junk " dna would seem to defy evolutionary logic

    根據理論說明，可以觀察到出現比例很高真正非功能性垃圾「 dna 」就好象是違反進化邏輯的。
