查询词典 mutations

Chromosome mutations can occur naturally but their frequency is increased by the effect of x-rays and chemical mutagens.

染色体的突变是自然发生的，但通过 X 射线或化学诱变剂可以增加突变的频率。

However, environmental mutagens can also induce mutations at undamaged sites and result in the so-called nontargeted mutagenesis.

但是环境诱变剂引起的突变也可发生在非DNA损伤部位，它被称之为非定标性突变。

There were gene mutations of TGF-1 in SOSP-9607,which might play an important role in pathological mechanism. The gain of muton with strong functional activity is very important for the repair of bone and cartilage injuries.

人成骨肉瘤细胞系SOSP-9607中存在TGF-β1基因突变，其可能在病理机制中起重要作用，具有强功能活性突变子的获得对于骨软骨损伤的修复有重要意义。

For example, when passing at low altitude supersonic aircraft, when the head and tail of the aircraft will have the pressure and density of mutations through the surface formed after the N-shaped shock wave reflection, reached the ground sounds like explosions, this special sound of noise is called the H -.

例如，当超声速飞机在低空掠过时，在飞机头部和尾部会产生压力和密度突变，经地面反射后形成N形冲击波，传到地面时听起来像爆炸声，这种特殊的噪声叫做轰声。

Based on the structure, those human diseases related mutation sites are mapped onto the structure accurately. As a result, it is found that these sites are all around the electron transfer prosthetic groups or ubiquinone. And these mutations will alter prosthetic groups' binding or ubiquinone's binding, causing electron leakage from the prosthetic groups in the electron transfer chain, producing reactive oxygen species and leading to tumor formation.

利用线粒体复合物 II 的结构对已知与人类疾病相关的该复合物突变位点进行了精确定位，发现这些突变位点均位于电子传递体或辅酶 Q 结合位点的周围，它们的突变或影响了电子传递体的结合，或影响了辅酶 Q 的结合，从而导致电子传递的中断，电子逃逸到线粒体基质中或线粒体内膜中，经过一系列下游途径导致疾病的产生。

This model (designated TnI-203/MHC-403) was generated by crossbreeding mice with thae Gly203Ser cardiac troponin I (TnI-203) and Arg403Gln -myosin heavy chain (MHC-403) FHC-causing mutations.

这个模型(被称为TnI-203/MHC-403)是通过Gly203Ser心肌钙蛋白I(TnI-203)和Arg403Gln -肌球蛋白重链(MHC-403)致FHC基因突变的杂交所得。

Detection of new PTEN/MMAC1 mutations in head and neck squamous cell carcinomas with loss of chromosome 10［J］.

抑癌基因PTEN在胃癌细胞中的表达及意义［J］。

Noggin induces the nerve tube formation. It binds and inactivates members of the transforming growth factor-beta superfamily signaling proteins, such as bone morphogenetic protein-4 (BMP4). Proximal symphalangism (SYM1) and multiple synostoses syndrome (SYNS1) are related to noggin mutations.

Noggin能使紫外线人工腹侧化的爪蟾胚胎重新恢复背-腹的身体轴；在神经系统中诱导神经管的形成；减弱包括骨形态发生蛋白在内的转化生长因子信号蛋白的活性，从而控制骨的生长；调控生殖系统的发育。

Laboratory research has shown that UV radiation from either the sun or tanning devices can cause oncogenic mutations in skin cells, and use of sunbeds has also been associated with increased risk for melanoma and squamous cell carcinoma.

实验室的研究已经显示，无论是来自太阳还是室内晒黑装置的紫外线都能够造成皮肤细胞的突变，并且在晒日光浴也能够增加乳癌、黑色素瘤、鳞状细胞癌的患病几率。

You can think of the Chaos mutations as stances.

你可以把混沌变异体看作姿态。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
