使杂交

As RNA polymerase moves along the DNA template, it unwinds the duplex at the front of the bubble, and rewinds the DNA at the back. The length of the transcription

当RNA聚合酶沿DNA模板移动时，它打开泡前的DNA双螺旋，并在复链点使DNA复原，转录泡的长度随增长反应阶段而异，在12-20bp之间，但其中的RNA-DNA杂交体区域比这个长度要短。

In response to extracellular stimuli, ERK1/2 translocates to nucleus, phosphorylates transcription factors,such as Elk1,ATF2,Sap-1α,c-myc,STAT, and so on, co-regulators and chromatin proteins to initiate transcriptional changes.

斑点杂交研究发现Ngb mRNA在大脑皮层、海马和丘脑等部位表达，缺血缺氧可使Ngb mRNA表达上调，其表达上调程度与相应区域对缺血缺氧的耐受性呈正相关。

However, the hybrid aircraft's design necessitates a large body to allow for the gas containment chamber.

但是，杂交飞机的设计，需要一个大机构，以使气体遏制厅。

A great part of flyball's popularity stems from the fact that it is one of the competition activities available to mixed-breed dogs, allowing rescued mutts and non pedigree dogs to shine alongside their purebred canine friends.

飞球比赛之所以很受欢迎的很重要的一个原因是杂交犬只也能够参加比赛，这使那些非纯种犬也能在与纯种犬一样在比赛中大放异彩。

Our province has successfully developed and produced in a manner of industrialization the genetic engineering human insulin, so that our country become the world's third country to master this technology. In 2002, the Jilin Academy of Agricultural Sciences produced the world's first hybrid soybean variety.

我省研制成功并产业化生产基因工程人胰岛素，使我国成为世界上第三个掌握该技术的国家。2002年，吉林省农科院培育出世界上第一个杂交大豆品种。

Using a three-strand hybridization system, we were able to conjugate oligonucleotides modified Fe2O3 and Au nanoparticles.

经由杂交所形成的复合物(Au/Fe2O3)，在加热至70℃的温度下，会破坏氢键，使复合物(Au/Fe2O3)分开，而回溶於水溶液中。

In a breeding system of commercial Imitative Local Broiler, using the Jiang-13 strains of white Plymouth Rock and Guangdong Local breed crossed with each other to produce a hybrid with rapid growth, high flavour of meat and buff feather similar to the local breed of Guangdong, the Jiang-13 strain must be of recessive white feather and, also,under the coucealment of recessive white feather, its most ideal genotype will be ees~+s~.

为了利用江-13白洛克品种鸡的优良肉用性状，用以和优质地方黄羽鸡种构成优质高产的肉鸡繁育体系——广源鸡繁育体系，使商品肉鸡具有与广东地方鸡羽色相似的浅黄羽色，参加杂交的江-13白洛克鸡必须是隐性白羽，而且基因型为iiccOObbeess最为理想。

AI can be used in non-hybrid matings when the situation dictates, such as when a mating pair has not produced offspring after several months of co-habitation.

在某些时候人工受精技术会使用于不同类型的纯种剑尾鱼之间的杂交，例如一对杂交种鱼经过了几个月的同缸生活后还是没有生产后代。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
