MITOCHONDRIAL DNA POLYMORPHISM IN CONTROL REGION FROM CHINESE YUGU POPULATION

Objective To investigate the mitochondrial DNA sequence polymorphism sites in Chinese YUGU ethnic group and to provide basic data used in forensic purpose. Methods Genomic DNA was extracted from the hole blood of 100 unrelated individuals of Chinese YUGU ethnic group by standard chelex-100 method. The sequence polymorphism sites was determined by PCR amplification and direct sequencing. Results 54 polymorphic sites were noted in mtDNA np16091-16418 region, and 46 haplotypes were identified. The genetic diversity was calculated to be 0. 9691, and the genetic identity was calculated to be 0. 0406. Conclusion There are some particular polymorphism sites in Chinese YUGU ethnic group. The results suggest that sequence polymorphism from np]6091 -- 16418 in human mitochondrial DNA can be used as a biological marker for forensic identity.     

谁来终结"种族"歧视

新年伊始，面对多年来挥之不去，盘旋在小排量汽车上空的“种族”歧视阴影，国家发改委等六部委联合发出通知，以强硬的姿态要求各地必须在三月底前“为小排量汽车解除在行驶路线中的不公平待遇”，颇有一点“横刀立马，力挽狂澜”的气势。     

从珍妮的“头发”看她的爱情与人生经历

"头发"的意象经常出现在西方各种文学艺术作品当中,成为作家艺术家塑造人物、表现主题常用的手段。在小说《他们的眼睛望着上帝》中赫斯顿巧妙地以主人公珍妮的头发为线索,通过珍妮成长过程中的经历,表现了黑人女性在性别歧视和种族歧视双重压迫下艰难的生存境地,表达了作者渴望建立在平等、和谐、共存基础上的两性关系和种族关系的强烈愿望。本文沿着珍妮的头发这条线索,从性别、种族两个方面来解读赫斯顿独特的女性主义意识和种族意识。     

种族偏见

有些汽车生而伟大,披覆着所有人期待的目光诞生;有些汽车生而坎坷,努力提升却始终得不到市场的青睐;更多的汽车生而平庸却能取得难以置信的市场销售成绩……是什么导致了这些情况的发生?仅仅因为它们的"种族"不同吗?     

谁是谁的蝴蝶夫人

这几乎是一个不可能的故事:冷战时期,一个男性法国外交官迷恋上一个中国京剧演员,他们热烈相恋,在一起生活了20年,还生下了一个孩子,可结果却是,他发现她是一个男人。故事荒诞得让人不敢相信,即使是作者黄哲伦本人,在后记中谈到情节的真实性问题
