查询词典 DNA

The number of un-repaired DNA damages is thimbleful, but these un-repaired damages maybe produce very important influence on organism. In the replication process, DNA damage can lead to gene mutation.

为保证机体生理活动的正常进行、生命过程的延续和遗传的稳定性，生物体内形成了一整套相当完善的修复系统，可使DNA的损伤得到最大限度的修复。

In a study of New Zealand's "living dinosaur" the tuatara, evolutionary biologist, and ancient DNA expert, Professor David Lambert and his team from the Allan Wilson Centre for Molecular Ecology and Evolution recovered DNA sequences from the bones of ancient tuatara, which are up to 8000 years old.

在研究新西兰"活恐龙"刺背鳄蜥的过程中，同为进化生物学家和古遗传专家的大卫·兰伯特教授以及他来自艾伦·威尔逊分子生态与进化中心的团队鉴定出，从古代刺背鳄蜥骨骼中提取分析所得的DNA序列竟有8000年之久。

Results Hypericin(75w tungsten lamp,10 min of light exposure,2μg/ml)had obvious cytotokic ef- feet on C6 cells, and the specific DNA...

结果金丝桃素在低剂量2μg／ml时，75W钨灯光照10min，即可对C6细胞株具有细胞毒作用；抽提其DNA做琼脂糖凝胶电泳可显示凋亡特有的DNA"阶梯"。

With the development of single moleculer manipulation.Much research work has been done on DNA by optical tweezer, magnetic tweezer, micropipe, and so on. All these work has opened a new area in molecuer biology.

随着单分子操作的实验技术的发展，人们通过光镊、磁镊、微吸管等等，研究DNA分子的力学性质，探索DNA与蛋白质的相互作用，为分子生物学的研究开辟了新的天地。

PNAs are uncharged DNA mimics, which are resistant to nucleases and peptidases, and hybridize with complementary DNA and RNA with high affinity.

PNA是一类不带电荷的DNA相似物，不受核酸酶和肽酶的作用，可以和cDNA、RNA高亲和性杂交。

Unicolor provides us a set of improved parameters based on the rata of fruit and embryo seeds.After pollinating the conclusion of the items of ovary enlargement, fruitfulness, embryo seeds of transferring exogenous DNA should be better transferred to Lilium davidii var.

在导入时，通过对授粉后4个时间段滴加外源DNA的子房膨大、结实和有胚种子情况的研究后得出结论，选择外源DNA滴加的时机在授粉后3h左右较为适宜，此时的子房膨大率和有胚种子率均较高。

Therefore, the patents at issues directed to 'isolated DNA' containing sequences found in nature are unsustainable as a matter of law and are deemed unpatentable subject matter.

因此，讼争的专利不能得到法律的支持，故认为其没有专利性。因为，该专利所指向的被分离的DNA包含了自然状态下就已存在的DNA序列。

The fluorescence intensity of-DNA system was unquenched before and after the addition of CuL.

CuL与DNA作用后，氧化峰电流减小，式电位负移；溴化乙锭-DNA体系在加入CuL前后的荧光强度基本没有改变。

Originally, many of your geneticists thought this third strand was a vestigial remnant of some primitive RNA/DNA.

原先，你们的很多遗传学者认为这第三条是某些原始RNA/DNA的退化残余（译者注：就是科学家认为的垃圾DNA ）。

Do you know, i need you to come back

你知道吗，我需要你回来
