  5. I think it is legitimate to take a broader view, and include externally transmitted information, as well as dna, in the evolution of the human race

  7. It clearly allows us to engineer enzymes with novel functions and features by strategies, such as error - prone pcr, dna shuffling and stagger extension process ( step ), when very little is known about spatial configuration of proteins. therefore millions of years in nature can in principle be accomplished in the test within several years. according to the basic idea of directed evolution, we modified the a - aldc gene by error - prone pcr

    它不需要事先了解酶的空間結構和催化機制，而通過在體外模擬自然進化機制（隨機突變，重組和自然選擇） ，利用易錯pcr ， dna改組，交錯延伸等方法，改造酶基因，定向選擇（或篩選）有價值的非天然酶，短期內在試管中完成在自然界需要幾百萬年的進化過程。
  8. Tandem repeats play a variety of roles in gene expression, regulation and evolution, and are ideal marker in genetic mapping. further more, the techniqe of dna fingerprinting based on the polymorphism of tandem repeat is now widely used in various fields such as medical jurisprudence, etc. the more eye - catching discovery is, in recent years, that some genetic diseases are related with certain trinucleotide repeats

    串聯重復在基因表達、調控和遺傳等方面起著十分重要的作用，同時它因具有高度多態性，已成為基因組遺傳圖譜和物理圖譜的理想界標，另外以串聯重復為基礎的「 dna指紋技術」在法醫學等領域廣泛應用。
  9. There has been no detectable change in human dna, brought about by biological evolution, in the ten thousand years of recorded history

    在有文字記載的歷史的這一萬年間，在人的dna中不存在由生物進化帶來的可察覺的變化。 （人的脫氧核糖核酸沒有變化。 ）
  10. It is usually used to study the evolution of the sequences from a common ancestor, especially biological sequences such as protein sequences or dna sequences

    這一方法常用於研究由共同祖先進化而來的序列，特別是如蛋白質序列或dna序列等生物序列。
  11. These conclusions are expounded on the basis of the peculiarity of cube and regular tetrahedron of dna sequences, so they are rationalization, and they will be very useful in the study of the classification and the evolution of organisms

    它們都是根據dna序列的立方體和正四面體的性質而提出來的，有一定的合理性。本文的結論對人們研究生物體的分類和進化有著很重要的作用。
