The single nucleotide polymorphism of growth hormone gene was investigated in various breeds of duck, including Beijing ducks, Xihu mallards, Jinding ducks, Shan Partridge ducks, Jingjiang ducks and Shaoxing ducks. The primers for intron 2 and 3 in GH gene were designed based on the database of duck genomic sequence and the SNPs were detected by PCR-SSCP method.

根据鸭生长激素基因内含子2、3的序列设计5对引物，利用PCR-SSCP方法对北京鸭、西湖野鸭、金定鸭、山麻鸭、荆江鸭、绍兴鸭等6个鸭品种进行了单核苷酸多态性分析，并检测其多态性。

Drain treatment powder HR--212 This product is prepared from special chemicals,and it contains decomposer that can decompose high fat substance,ground meat,rage,hair and plant fiber,thus it can unblock drains.

餐饮系列通渠粉 HR----212 本品是由特殊化学药剂制成，内含有腐化剂，其效力可使高脂肪物、碎肉、碎布、毛发及植物纤维等分解腐化，使管道恢复畅通。

However,there was no difference in the frequency of genotype and phenotype for the two alleles of C 3b R between RA patients and healthy volunteers.

已经发现，在红细胞内含有多种与免疫有关的物质，具有识别和提呈抗原，加速免疫复合物的清除等生物功能。

Prolactin receptorgene was studied as a candidate gene for the prolificacy of Jining Grey goats. Eight pairs of primers were designed to detect single nucleotide polymorphisms of exon 3 to exon 9 and intron 9 of PRLR gene in both high fecundity breed and low fecundity breeds (Liaoning Cashmere goat and Angora goat) by PCR-SSCP.

设计8对引物，采用PCR-SSCP技术检测催乳素受体(prolactin receptor，PRLR)基因外显子3至外显子9和内含子9在高繁殖力山羊品种和低繁殖力山羊品种（辽宁绒山羊、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 split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
