The possibility of researching gene mutation with the technique of gene chip was discussed. A new imagination to randomly determine DNA sequence in different living beings with the technique of gene chip was advanced. In this way, whether the encoding sequence gene in DNA of eukaryon organism has some regularity was studied.

进而提出新设想——采用基因芯片技术对不同生物群体随机抽样进行DNA测序，从而探讨在真核生物DNA分子链上编码序列遗传基因的变化是否有规则而非随机的，非编码序列遗传基因是否为生物进化过程中曾经有表达能力的结构基因，并分析可能获得的结果。

In a word, we extracted first cotyledon of buckwheat total RNA, by method of RT-PCR and 3RACE, get the C terminal cDNA sequence of PI from Ukraine buckwheat, and do some bioinformatics analyse on this cDNA sequence of PI from buckwheat, such as gene characteristics, expression mode. All of this will be help for the forward research on functional protein and high performance of procaryon expression or eukaryon expression.

综上所述，我们利用RT-PCR和3′RACE技术首次从吉乌一号甜荞第一对子叶中克隆获得荞麦蛋白酶抑制剂基因并对其基因特性、表达模式进行生物信息学分析，同时构建了该基因序列羧基端原核表达载体，为今后进一步研究荞麦功能性蛋白的分子机制及高效原核、真核表达载体的构建奠定了基础。

On the basis of the basic principles of sequence stratigraphy,the formation of cyclical sedimentary stratum is driven by eustasy which is periodic,and by analysing the seismic,well log and nano-microfossil data of Pearl River Mouth Basin,an integrated study was conducted which is on the sequence stratigraphy of lower and middle Miocene stratum within and around Kaiping Sag .

以层序地层学基本原理——周期性海平面升降控制旋回性地层沉积——为指导，根据地震、测井和古生物资料，对珠江口盆地开平凹陷及其围区的早中新世—中中新世地层进行系统的层序地层分析，认识到该区的层序地层学特点取决于其特殊的古地理位置。

Extracting exonic sequences directly from genomic sequence is difficult, but ESTs have provided a convenient means of accessing them. An expressed sequence tag is part of a gene that results from sequencing a portion of a cDNA clone that was generated from an mRNA.

从mRNA来源的cDNA文库中随机取出一个克隆，从5'末端或3'末端对插入的cDNA片段进行单向测序，所获得EST为我们研究基因表达提供了方便快捷的手段。

Kobayashi had analyzed the relationship between genetype and BMD of 238 post-menopause healthy femmes at Nagano county in Japan,and pointed out:the abdominal vertebra the Z integral of BMD has correlation with PvuⅡsite,the corresponding BMD\' s sequence of each genetype is: PP＜Pp＜pp,the Z integral of PP genetype in abdominal vertebra BMD is the lowest,but the corresponding BMD\' s sequence of Xbal polymorphic site genetype is XX＞Xx＞xx,without statistical significance.

Kobayashi等分析日本Nagano县238名绝经后健康妇女基因型与BMD的关系发现：腰椎BMD的Z积分与PvuⅡ位点相关，各基因型对应的BMD高低顺序为PP＜Pp＜pp，PP基因型腰椎BMD的Z积分最低，而XbaⅠ多态位点基因型对应的BMD高低顺序为XX＞Xx＞xx，但无统计学意义。
