2.(=deoxypentose-nucleic acid)去[脱]氧戊糖核酸
1.[Biochemistry](=deoxyribonucleic acid)
2.(=deoxypentose-nucleic acid)
1.deoxyribonucleic acid: a chemical substance that contains genetic information and is found in all living cells and some viruses
2.the combination of features that make something what it is
1.Genetic profiling compares DNA at a crime scene with that of a known suspect or with other profiles in a database in search of a match.
利用基因识别，我们可以将在犯罪现场采集到的DNA与已知嫌疑人作比，或者在数据库中寻找其他与信息相符的资料。
2.Within the last 200, 000 years, we all share an ancestor, a single person, Mitochondrial Eve -- you might have heard about her -- in Africa.
DNA把历史弄得很清楚，在过去的二十万年中，我们有共同的祖先，同一个人，线粒体Eve—你可能听说过她—在非洲。
3.Some of these electrons travel through the DNA forest and are fed into a device that measures their spin polarization.
其中的一部分电子穿过DNA“森林”后，注入一个可以测量其自旋极化率的仪器中。
4.That is a part of their DNA and the hard truth, no matter how much women may hate or despise this fact.
这一部分是由他们DNA所决定，女人再怎样厌恶或是轻视这个事实，都无法改变这个硬道理。
5.So far the project has unearthed no sign of any genetic pattern that would suggest DNA transfer between the two hominid lineages.

6.Criminals already have to be careful not to leave fingerprints or DNA that could incriminate them.
罪犯已经不得不小心地使自己不留下指纹或者DNA，这些线索可以指认他们。
7.They said they were horrified by the error, with one saying she would consider a DNA test once her baby was born to check if it was hers.
他们说他们被这个错误吓坏了，其中一个人说一旦她的孩子出生了他将考虑通过DNA测试以便确定孩子是不是自己的。
8.The number of these circular DNA molecules - known as signal joint TCR excision circles (sjTRECs) - declines at a constant rate with age.
这些环状DNA分子叫做信号结合T细胞受体删除DNA环，其数量随着年龄的增长按固定比率减少。
9.As you can see , the body is being carefully exhumed for transportation to a facility where DNA can confirm the identity .
你可以看到我们身后，尸体正在被小心地挖掘出来，将要被送去医疗机构进行DNA鉴定以确定身份。
10.And it doesn't seem to me that there is grass-roots, broad support for the behavior of diplomats, say, stealing [inaudible] DNA.
