染色体基因

Genetic heredity experiments showed that the inheritance of the melanic characteristics was incomplete dominance and autosomal and followed the Mendalian law.

结果表明，SEM蛹黑化性状的遗传是不完全显性遗传，遵循孟德尔的不完全显性遗传规律，控制黑化性状的基因位于常染色体上，与性染色体无关。

Interspecies hybridization and backcrossing is a means to transfer desirable genes from one species to another in breeding programs of higher plants. Monosomic alien addition lines can be produced via addition of single chromosome of an alien donor species to the entire chromosome complement of the recipient species.

在高等植物中，以种间杂交和回交把有益基因从一个物种转移到另一个物种为目的育种项目中，单个外源染色体常常被附加到含有受体细胞完整一套染色体中，形成异源单体附加系。

Secondly the product of the DOP-PCR of Y1,Y2,X+4,1 chromosome of Muntiacus crinifrons were used as the templates of the next amplification using the special primer devised according to the human SRY gene .

再以黑麂的Y1，Y2，X+4和1号染色体的DOP-PCR产物为模板，用人的特异性的SRY（sex determining region of the Y chromosome）基因引物对其进行扩增，结果表明黑麂只有Y2染色体出现了SRY扩增片段。

This first comprehensive analysis includes genes and proteins and their relation to human disease, repeated sequences, comparative genome-wide studies of mammalian orthologous chromosomal regions and rearrangement breakpoints, reconstruction of ancestral karyotypes and the events leading to existing species, rates of variation, and lineage-specific and lineage-independent evolutionary events such as expansion of gene families, orthology relations and protein evolution.

这次全面分析包含了三种动物的基因组序列和蛋白产物以及它们与人类疾病相关性分析，重复序列，哺乳动物同源染色体区域和重排断点的比较基因组研究，祖先核型的重建，产生现有种群的事件，变异率以及种系特异和不依赖种系的事件如基因家族扩展，同源关系以及蛋白进化。人类19号染色体序列被破译了。

RT-PCR detection of SYT-SSX mRNA can be used in formalin-fixed, paraffin-embedded tissues as a sensitive and specific technique in the diagnosis and differential diagnosis of synovial sarcoma. 2. The SYT-SSX fusion type is related to histological type and cell proliferative activity of synovial sarcoma. 3. Some characteristic sequence motifs flank genomic breakpoints of chromosomal translocation of synovial sarcoma, including Alu sequences, Translin recognition sequences, topoisomerase Ⅱ recognition sites and palindromic sequences, which may be associated with chromosomal translocation of synovial sarcoma.

1、RT-PCR技术检测SYT-SSX mRNA表达可用于福尔马林固定、石蜡包埋组织，敏感性和特异性高，可用于滑膜肉瘤诊断和鉴别诊断。2、SYT-SSX融合基因类型与滑膜肉瘤组织学分型及细胞增殖活性相关。3、滑膜肉瘤染色体易位断裂点旁存在一些特征性序列，包括Alu序列、易位素识别序列、拓扑异构酶Ⅱ识别位点、回文序列等，可能与其染色体易位发生机制有关。

In the end of this paper, the research advance of stress resistance gene location on the fourth chromosome set of Triticum was discussed.

最后讨论了小麦种、属第4部分同源群染色体抗逆性基因定位的研究进展，并强调应重视对小麦种、属第4部分同源群染色体的研究和利用。

SATB1 folds and remodels the chromatin -- the intertwined DNA and proteins that form chromosomes -- into new shapes, bringing even distant parts of the genome together for coordinated control of gene expression_r and regulation.

SATB1打开并重新改型这些染色体——使DNA和蛋白质缠绕而形成同源染色体——变成新的形状，使位置较远的基因组结合从而协调基因的表达和调控。

Fluorescence staining of cell framework and nuclei were conducted, the result of which revealed that the transfected cells displayed disorder in cell skeleton, shrinkage and cleavage in nuclei. It was illuminated that chromosome DNA occurred cleavage and fragment since the result of TUNEL detection was positive. The transfected cells also displayed more typical apoptotic character, including exposure of phosphatidylserine in the plasma membrane by Annexin V staining detection, shrinkage nuclei, chromatin condensation, plasma membrane blebbing and chromatin breakage fragments by electron microscopy analyses.

细胞骨架和细胞核染色结果表明，AIF基因转染细胞呈现细胞骨架的紊乱、细胞核固缩、分裂等变化；TUNEL检测呈阳性，说明有染色体DNA出现断裂；Annexin V染色检测到转染细胞出现胞膜磷脂酰丝氨酸的暴露；电镜观察的结果显示，转染目的基因组细胞呈现细胞膜出泡、细胞核固缩、染色体凝集和断裂等典型的凋亡细胞特征。

The point of contact between paired chromatids during meiosis, resulting in a cross-shaped configuration and representing the cytological manifestation of crossing over.

染色体交叉在减数分裂过程中成对的染色体之间的接触点产生一种交叉形状的构造，代表着基因互相交换的细胞表现形式

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！
