一种由深圳赛百诺基因技术公司――一家中国公司，所使用的方法就是用正常的肿瘤抑制基因置换破损的肿瘤抑制基因。
One approach, used by Shenzhen SiBiono GeneTech, a Chinese company, is to replace broken tumour-suppressor genes with the correct version.
科学家已经知道alk的异常和淋巴瘤还有肺癌的的发病有关。ALK的异常引起染色体之间DNA的置换，从而引起新的癌症基因的突变。
Scientists already knew that abnormalities in ALK were linked to lymphoma and lung cancer, where it triggers the translocation of DNA between chromosomes to make new cancer-causing genes.
最初大家都只知道它的序列很短，是极其微小的RNA控制片断，大家叫它为反义RNA，它通过置换作用而阻止抑制基因的活性，从而阻碍密码子的转录与翻译活动。
It was previously known that short, tiny control RNA, called antisense RNA, can stop the activity of genes by placing themselves so that "reading" of the code is impeded.
目的观察血浆置换技术在ABO血型主侧不合的非亲缘异基因供髓骨髓移植中的应用价值。
Objective To explore the value of plasma exchange in preventing the hemolysis of ABO-incompatible unrelated donor bone marrow transplantation.
进化酶基因的DNA测序表明4 186含两个有义氨基酸置换：k16 7r和S374C，二者既不位于底物结合位点，也不位于酶的金属离子结合位点。
DNA sequence revealed that 4-186 contains two amino acid substitutions, K167R and S374C, both of which locate neither the substrate - binding sites nor the metal - binding sites of EAP.
