Part I Cbx4 promotes SUMO modification of DNA methyltransferase 3a Dnmt3a is one of de novo DNA methyltransferases in mammals, which are responsible for the generation of somatic methylation patterns during embryogenesis and gametogenesis.

第一部分：Cbx4促进DNA甲基转移酶3a的SUMO化修饰 Dnmt3a是哺乳动物中的一个起始性甲基转移酶，负责在胚胎发育和配子发生过程中创建各类细胞的甲基化谱式。

Can accelerate the bone marrow cell from G1 phase into S phase when we measure it's Cell cycle, it make S phase rate was increased .thus it promoted DNA synthesize and repaired. Mice irradiated at dose of 5.5 Gy gamma-irradiation showed timed-related decreases and restores in peripheral blood picture at day 1 through day 21, the counts of WBC of these group had taken drug has various degree to increase than irradiation control group in day 1. Grugs failed to protected the peripheral blood cell at lowest point, but seems promote their rescovery.9803 treated group was distinct. At 7days after mice were radiated in 3.5 Gy. we observed drug can Significantly hold back the decreased number of hematopoietic progenitors colony forming radiation induced. These findings indicated 9803 have a certain radioprotective activity against gammer irradiation in mice.

给药组的 CFU-S 数量较照射对照组明显增加，3.5Gy 照后第七天观察给药9803组对小鼠骨髓造血组细胞集落生成能力的影响，给药组的造血祖细胞集落的形成能力强于照射对照组，并且9803组明显优于523组。5.5Gy 照射引起的小鼠的外周血细胞数量的降低以 WBC 发生最早，照后24小时给药组的 WBC 数量均比照射对照组有不同程度的升高，以9803各给药组最为明显，药物未能使照射引起的外周血细胞最低值升高，而有降低的趋势，但给药对照射后期外周血象的总体恢复有较好的促进作用。7.5Gy 照射后第七天测定小鼠骨髓细胞周期的测定中发现9803具有促进骨髓细胞由 G1期进入 S 期的效应，致使 G0/G1期细胞显著减少， S 期细胞比率显著增加，这利于促进 DNA 合成修复，即促进骨髓细胞增殖，骨髓细胞 DNA 含量给药组显著高于照射对照组。

Finally, the calculation process of CGR graphic's multi-fractal analysis was studied. the scope of choice of the weight factor and the scale invariance range were discussed, the weight factor can be chosen as ? 15≤q≤50; multi-fractal spectrum and generalized dimension of different sequence were calculated, multi-fractal spectrum and generalized dimension in different scales of different sequences were compared, it was found that multi-fractal spectrum and generalized dimension can show different levels of fractal characteristics of CGR graphics of DNA sequence, which can distinguish more complex structure of sequences.

最后，研究了DNA序列CGR图形的多重分形的计算过程，讨论了权重因子及满足标度不变性的范围选择等问题，得到结论：对CGR图形进行多重分形时权重因子可以选择为-15≤q≤50；计算了不同序列的多重分形谱和广义维数，比较了不同序列不同尺度的多重分形谱和广义维数，发现多重分形谱和广义维数能够表现DNA序列CGR图形的不同层次的分形特征，能够区分更复杂的序列结构。

T-DNA, carrying vector sequences, integrated into rice genom e. These seem ingly suggested that the IR

切会发生在T-DNA 区域外的载体序列上，使T-DNA 带上了区域外的载体序列整合到水稻基因组中

The genomic DNA was extracted from all peripheral blood samples using guanidine hydrochloride method.

使用盐酸胍DNA抽提法提取所有外周血样本的基因组DNA。

The study indicated that RAPD technique is useful and practical for the identification between gynogenesis fish and hybrid individuals.RAPD and AFLP technique were used to screen the sex-related DNA marker through analyzing the DNA differences between female and male of Jian carp.

通过对反应条件的优化处理，在引物E-ACG／M-CAA的扩增图谱中找到一条雌性特异的DNA条带，分子量约323bp，雄性个体均无此条带，初步发现了雌雄之间的遗传差异，可为建鲤遗传性别的鉴定提供参考；同时发现某些位点在雌性和雄性个体出现的比例存在很大差异，推测与遗传性别有一定的关联。

Those DNA bands expressed in female parent but not in male parent also expressed in gynogenesis filial; DNA bands expressed in male parent but not in female parent didn抰 express in gynonensis, while normally expressed in dcploid control fish.

证明牙鲫雌核发育子代的遗传物质来自母本，雌核发育诱导使用的精子经过紫外线灭活后，遗传物质己被破坏，其携带的遗传信息没有传给子代，在DNA水平证明了雌核发育诱导方法和结果的可靠性。

We examined the effects of Gyp on human leukemia HL-60 and mouse WEHI-3 cells. Therefore, the results from flow cytomertic analysis indicated that Gyp arrest cell cycle in G0/G1 and induced apoptosis in both examined cell lines. We also used DAPI stain and DNA gel electrophoresis to confirm Gyp induced apoptosis in both cell lines.

本实验探讨绞股蓝皂甘是否对於人类血癌细胞株（HL-60）和小鼠血癌细胞株（WEHI-3）诱发抗癌活性机转，藉由流式细胞仪分析结果发现绞股蓝皂甘能够让细胞周期停滞於G0/G1期，最后走向细胞凋亡，此结果可经由DNA电泳观察到DNA断裂情形得到证实。
