1.The β-globin gene locus control region (LCR) consists of four erythroid-specific DNase I hypersensitive sites (HS1-HS4)which are necessary for the high level expression of globin genes in erythroid tissues.
β-珠蛋白基因簇位点控制区(Locus Control Region, LCR)位于ε-基因上游，由四个红系特异性的DNase Ⅰ高敏位点(HS)组成，它们对于β-珠蛋白基因簇内各个珠蛋白基因在红系组织细胞中的高表达是必需的。
2.METHODS: Based on the amino acids sequence of Arnt2 (LOCUS:NP_036913), the subcellular localization of Arnt2 in eukaryotic cells and the nuclear export signals (NES) of Arnt2 were predicted in CBS bioinformatics database.
方法:利用CBS生物信息资源,根据Arnt2氨基酸序列(LOCUS:NP_036913)进行真核生物亚细胞定位预测,并寻找Arnt2核输出信号(NES);
3.When the F1 plants were selfed,and the silencing locus and the homologous locus were separated in some progenies,42 of the 200 progenies exhibited DhlA activity,and 158 no DhlA activity, and the proportion of the DhlA-expressing plants to the dhlA-silencing ones was 3.76 to 1,which suggested that the silencing locus inactivated in trans the homologous transgenic locus as a Mendelian dominant factor.
将F1代植株自交 ,使部分沉默位点与反式失活的同源转基因位点分离 ,结果 2 0 0株子代中有 42株表现DhlA活性 ,15 8株无DhlA活性 ,即dhlA沉默植株与表达植株之比为 3 .76∶1,表明沉默位点是以孟德尔显性因子方式使同源转基因位点反式失活的 .
4.The results showed that three genes such as HbB at Hb locus, TfC at Tf locus, Es- at Es locus diplayed certain correlation to the prolific trait of Small-tail Han sheep. Possibility of Ep to be used as the genetic marker should depend on further researches. The other four protein of AIb, Pr, AMY, LDH had no correlation to the prolific trait of Small-tail Han sheep, and couldn?t be used as the genetic marker.
结果表明:Hb位点的HbB基因、Tf位点的TfC基因、Es的Es-基因与绵羊多羔性可能存在相关性,Ep是否可以作为小尾寒羊多羔性的遗传标记,还需进一步探讨,其它4个蛋白(酶)AIb、Pr、AMY、LDH与绵羊多羔性不相关;
5.The additive effect of Glu-Bi locus was the same important as the interactive effect among Glu-B, locus and Glu-D1 locus on falling number.
对降落值以1B的加性效应和1B×1D的互作效应为主；
6.The effect of 7 + 8 on sedimentation value was more important than that of 7 + 9 and 22 in IB locus with same subunit in 1A locus and ID locus.
在1A和1D位点上亚基相同时,含有7+8的亚基组合,其沉降值高于含有7+9和22的亚基组合.
7.Within coding region,mtMSI was detected in 4 specimens,3 of which at locus ND1 and 1 of which at locus ND5 respectively,none at locus COICOIII.
有4例编码区检出mtMSI，微卫星ND1位点1例（2.22%），微卫星ND5位点3例（6.67%），其中3例同时合并有D-loop区mtMSI； 微卫星COI、COⅢ位点未检测到mtMSI。
8.2. 8 microsatellite loci linked daily gain QTL (SW524 and SW58 of them linked back fat thickness QTL) generated a total of 114 alleles in seven pig populations, means number of alleles per locus is 14.25. Mean polymorphism information content(PIC) per locus is from 0.6121 to 0.8020( > 0.5). Mean effective number of alleles per locus is from 3.185 to 6.144(>2).
2．8个微卫星位点均与影响日增重QTL连锁，其中SW524、SW58还与影响背膘厚QTL连锁，它们在7个群体中共检测到114个等位基因，每个位点平均14.25个，每位点平均有效等位基因数为3.185—6.144，均大于2，每位点平均多态信息含量为0.6121—0.8020，均大于0.5。
9.In the r-t diagram, where t is the cosmic time and r is the radial co- ordinate defined as the proper radial distance divided by the scale factor, the locus of the incoming photon emitted at the big bang and reaching us now, r_(t), is a mirror image of the locus of the outgoing photon emitted at the big bang with r = 0, r+(t).
在用定义为径向距离除以尺度因子的径向坐标r和宇宙时间t的r-t图中,大爆炸时向我们发射、现在到达我们这里的光子的轨迹,r_(t),是大爆炸时我们向外发射光子轨迹,r+(t)的镜象。
10.Yield locus is analyzed when antenna is controlled under either PT mode or AT mode. Double trapezium velocity locus is designed for PT mode while the helix search algorithm is designed for AT mode.
