核苷酸

Thedideoxynucleotides act as chain terminators since they have no 3'-OHgroup on the deoxyribose which is needed by the synthesis step.

双脱氧核苷酸在脱氧核糖上没有聚合酶延伸链所需要的3'－OH基团，所以可被用作链终止试剂。从得到的PAGE胶上可以读出我们需要的序列。

The inhibinβA gene was studied as a candidate gene for the prolificacy of Jining Grey goats. According to the sequence of bovine INHBA gene, four pairs of primers were designed to detect single nucleotide polymorphisms of exon 1 and exon 2 of INHBA gene in both high fecundity breed and low fecundity breeds (Inner Mongolia Cashmere goat and Angora goat) by PCR-SSCP.

采用PCR-SSCP技术检测抑制素βA亚基基因（inhibin βA，INHBA）的编码区在高繁殖力山羊品种和低繁殖力山羊品种（内蒙古绒山羊、安哥拉山羊）中的单核苷酸多态性，同时研究该基因对济宁青山羊高繁殖力的影响。

The follicle-stimulating hormone beta-subunit gene was studied as a candidate gene for the prolificacy in Jining Grey goats. According to the sequence of ovine FSHβ gene, nine pairs of primers were designed to detect single nucleotide polymorphisms of 5' regulatory region, exon 1 and exon 2 of FSHβ gene in both high fecundity breed and low fecundity breeds (Liaoning Cashmere goat, Boer goat and Angora goat) by PCR-SSCP.

采用PCR-SSCP技术检测促卵泡素β亚基(follicle-stimulating hormone β， FSHβ)基因5'调控区、外显子1和外显子2在高繁殖力山羊品种和低繁殖力山羊品种（辽宁绒山羊、波尔山羊、安哥拉山羊）中的单核苷酸多态性，同时研究该基因对济宁青山羊高繁殖力的影响。

Et al.(2003) Crosstalk between Rap and Rac regulates secretion of sAPP alpha. Nat. Cell Biol. 5, 633-639. We now report that Rap1 can physically and specifically associate with the guanine nucleotide exchange factor STEF through its TSS region.

我们现在说的是Rap1可以通过它的TSS区域实质地并且特异与STEF因子的鸟嘌呤核苷酸的改变相关联。

The results of FOXC2 expression profile in human embryos suggest that mutations in FOXC2 gene could lead to cardiovascular and axial skeleton development defects in human, and there are novel polymorphisms of FOXC2 gene in Han people.

根据FOXC2在人胚的表达模式，提示该基因变异可能导致人心血管和中轴骨骼发育缺陷；在汉族人群可能存在新的FOXC2基因单核苷酸多态性。
