查询词典 chromosome

Here we show that a newly evolved sex chromosome contains genes that contribute to speciation in threespine stickleback fish.

基因定位研究显示，新形成的X染色体包含雄性求偶行为基因，而先祖X染色体既包含行为隔离基因，又包含杂交种雄性不育基因。

Because man can only inherit genes carried on the sex chromosomes while woman have 2 sex chromosomes, even if one of sex chromosome has defect, there is another one can take place for.

这是因为男人只能继承母亲身上一个X染色体的基因。而女人有2个X染色体，即使一个辨色基因出现缺陷，还有另一个基因可以顶替它的位置。

A sex chromosome where the male is the heterogametic sex.

一种存在于男性细胞内的异型配子的性染色体。

Nano-Fe_3O_4 can induce DNA single-strand breaks without significancy and can not induce micronuclei formation and percentage of apoptosis. Nano-Fe_3O_4 can aggravate the effect of CdCl2 on DNA single-strand breaks and chromosome damage in HepG2 cells. They showed synergistic effects on DNA single-strand breaks after the data were statistic analyzed.

结果发现CdCl2能引起DNA断裂损伤、微核率的增加和细胞凋亡率的增加；nano-Fe_3O_4能引起DNA断裂损伤增加，但无显著意义，未引起微核率和细胞凋亡率的增加；nano-Fe_3O_4能加重CdCl2的对细胞DNA断裂损伤和染色体损伤，且二者联合作用对DNA断裂损伤的结果经统计分析认为有协同作用。

The transcription-associated effects contribute to the overall skew through the uneven distribution of the coding sequences on the leading and lagging strands; the replication-associated effects, on the other hand, through the entire chromosome.

其中结合转录的效应对整体不对称性的贡献主要是藉由蛋白质转录序列在复制双股之间的分布所造成；结合复制的效应的贡献则遍及整条染色体。

RESULTS: No Chromosome somatotype aberration was found in 100 metaphases in the experimental group.

结果：①每只实验动物观察100个中期分裂细胞，均未见染色体型畸变。

Some characteristics of the novel gene YH1 was explored by bioinformatics. The YH1 gene was mapped on the chromosome 20 with the size of 7. 5 kb or so by blasting to genome database and this fragment size for YH1 gene coincided with the result of Souther blot. There were nine exon and eight intron.

利用生物信息学方法，在基因组数据库中比较，发现YH1基因存在于一个定位在20号染色体上7.293kb的DNA序列中，这与Southern blot结果相符。9个外显子被8个内含子隔开。

Simultaneous studies were conducted on bone marrow micronucleus and spermatocyte chromosome aberration in mice, yielding negative results and no evidence of mutagenic effects.

同时报道了小鼠骨髓微核和睾丸精母细胞染色体畸变试验研究的结果，即两项试验均为阴性，无致突变效应。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.
