染色体

The method will eventually converge to a near optimal solution and is relatively unaffected by the outliers.Ⅲ. Trilinear geometry estimation based on messy genetic algorithm: similar to the method of epipolar geometry estimation. Experiments show that it is more robust and precise than other typical methods, but takes more time to get the final result.Ⅳ.

ii基于混合遗传算法的对极几何估计：以最小的数据子集来构造染色体，利用染色体在某一位置上的基因冗余来提高遗传算法的选择能力，尽管这样会增加运算的复杂度，但却更有可能寻找到全局最优解，并且运算精度略高于中的算法。

The nasal bone was absent in 43 of 59 (73%) trisomy 21 fetuses and in three of 603 (0.5%) fetuses with normal karyotype.

在59名第21对染色体三体的胎儿中有43名(73%)出现了鼻骨缺失，在正常染色体组合的603名胎儿中有3名(0.5%)出现鼻骨缺失。

Methods Conventional banding techniques and FISH were used to detect trisomy 17,18 and 21 in 38 patients with acute lymphoblastic leukemia.

方法用 FISH方法和染色体G分带技术对比观察急性淋巴细胞白血病患者染色体的变化。

For different FAB subtypes,translocation was most common in M3 patients,detected in 58%;deletion was most common in M1,detected in 18%;and trisomy was most common in M5,detected in 29%.

在不同的FAB亚型中，M3患者发生染色体易位的比例最高，为58%；M1患者中发生染色体丢失的比例最高，为18%；而M5患者中发生三倍体的比例最高，为29%。

" Turner's syndrome: Chromosomal disorder (from the presence of only one sex chromosome, X, in all or some of the body's cells) that causes abnormal sexual development in females."

特纳氏症候群：可致女人性发育异常的染色体疾病(所有或某些体细胞中只具有1个性染色体X)。

" Turner's syndrome: Chromosomal disorder (from the presence of only one sex chromosome, X, in all or some of the body's cells) that causes abnormal sexual development in female s."

特纳氏症候群：可致女人性发育异常的染色体疾病(所有或某些体细胞中只具有1个性染色体X)。

Compared with the "three antibodies method", the sensitivity for detection of the signal of Y chromosome fluorescence in situ hybridization in brain tissue sections of mice was enhanced significantly by the direct tyramine signal amplification method.

结果 "三步抗体法"在脑切片检测Y染色体阳性信号的灵敏度和特异度分别为85.67％和100％；直接TSA法在脑切片检测Y染色体阳性信号的灵敏度和特异度分别为92.82％和100％。

Chromatin loop A region of uncoiled DNA, usually about 200nm long, that extends out in a loop from the chromosome.

染色体环：一段解聚的 DNA 区域，通常长度为200nm ，是从染色体上伸长的环状结构。

Unicolor is accepting the exogenous DNA pollen-tube pathway transferring, the embryo seeds rate would be higher with 50 ug/ml concentration solution and the neutral drip DNA solution could be advisable.The gel electrophoresis of protein of the variation of the number of chromosome dont show any difference between transgene plant and their parental generation.

对导入后代部分植株进行了蛋白质凝胶电泳，但在所做电泳中未能出现有蛋白条带的差异，同时对部分的导入后代植株和未进行导入后代植株根尖染色体进行了观察，在两种植株中均有染色体数目的变异，变异的频率基本相同。

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.

要是在劳改农场，你等着挨绳子吧！
