染色体

Objective To detect loss of heterozygosity at chromosome 8p21-p23 in adenocarcinoma of gastric cardia.

目的 研究贲门癌中染色体8p21-p23杂合性丢失的情况。

Comparison with hexaploid bread wheat, there were one or two different chromosomes in Xinjiang rice wheat.

细胞学研究的结果认为新疆稻麦有1～2条染色体与普通小麦不同。

But in hexaploid triticale x common wheat, they rely on the chromosome breakage and recombination.

而在其反交中，外源基因的导入则更多依赖于染色体的断裂与拼接。

In common wheat ^hexaploid triticale, the exogenous genes are transferred by means of homoeologous chromosome pairing.

在以普通小麦为母本的杂交方式中，部分同源染色体配对可能是外源基因导入普通小麦基础。

Hexaploid wheat has a lot of homoelogous gones in its genomes, and the main objective of wheat breeding is to get good phenotypes.

小麦是异源六倍体，其染色体组中存在着大量的同源基因，其育种的主要目标是获得可遗传的优良性状。

From the above results, it can be indicated that the genetic variation of D-genome in synthesized hexaploid wheat was abundant and could be used to improve the genetic diversity in wheat breeding.

因此，人工合成六倍体小麦D染色体组中存在丰富的遗传多样性，可以作为拓宽普通小麦遗传基础的新的遗传变异来源。

The study also shown that gene on D genome chromosome of hexaploid wheat suppress the expression of the long glume gene in dwarfing polish wheat.

同时还发现在普通小麦的D染色体组中，存在抑制长颖基因表达的基因。

The 92 alleles were used to calculate Nei's s similarity index and the genetic distance .It was also found that the mean genetic distance between 26 synthesized hexaploid wheat was 0.4955, which was obviously high.

遗传距离计算结果也显示，26份材料D染色体组之间具有较大的遗传差异，平均遗传距离高达0.4955。

Bacteria do not have true CHROMOSSOMES-linear pieces of and complexed with histone proteins.

细菌没有真正的染色体——线状的 DNA 与组蛋白的复合物。

The movement of a Holliday junction that causes different hybridizations between the homologous chromosomes.

指Holliday交叉的移动，它会引起同源染色体不同区段之间发生杂交。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
