查询词典 x chromosome

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。

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。
