The "central dogma "of molecular biology indicated that the direction of the genetic information flow is from DNA - RNA - protein. However, up to now, the central dogma has not obtained a sufficient theoretical support from cybernetics and information theory.

The "central dogma "of molecular biology indicated that the direction of the genetic information flow is from DNA - RNA - protein. However, up to now, the central dogma has not obtained a sufficient theoretical support from cybernetics and information theory. In addition, some special cases in biology, such as, although the scrapie prion is irreversibly inactivated by alkali, five procedures with more specificity for modifying nucleic acids failed to cause inactivation and when a resting cell is activated by some factors and division occurs, protein synthesis has begun before DNA synthesis etc., are also very difficult to explain clearly by the central dogma. A broad outline of a mechanism for reverse translation can easily be "designed", based on the normal translation process, and this serves both to prove that there is no fundamental theoretical reason for the central dogma, and to illustrate why the redundancy of genetic code is not a problem.

分子生物学的“中心法则”表明:遗传信息的方向是从DNA→RNA→蛋白质。然而,截止目前为止,中心法则仍未从控制论和信息论获得足够的理论支持。此外,生物学中的一些特殊情况,例如,虽然用碱可使羊骚痒病基因不可逆地失活,但用对核酸具专一修饰作用的5种方法却都未能使其失活;另外,当间期细胞被某些因素激活并造成分裂时,在DNA合成之前蛋白质的合成就已经开始等,也都很难用中心法则来解释清楚。基于正常的翻译过程,也能容易地“设计”一个逆翻译机制的大概轮廓,并且这种机制既可以证明为什么中心法则没有理论基础,同时又可以说明遗传密码的简并性。 本文根据作者先前的一些研究结果,从控制论、信息论和理论生物学的角度,通过对DNA和蛋白质所存在的遗传信息载体的特征进行理论比较和分析的基础上,就蛋白质作为遗传信息载体的可能性、氨基酸-密码子间可能的配对方式以及遗传信息流的方向等问题进行了探讨。作者推测,蛋白质也许可作为遗传信息的载体参加信息的传递;遗传信息的传递除了中心法则所描述的途径外,似乎还有另外的一条途径,即遗传信息沿蛋白质→DNA(RNA)→蛋白质的方向流动,这里也包括了中心法则所描述的遗传信息流。毫无疑问,有关蛋白质在遗传信息传...

UML (Unified Modeling Language) is one of the latest fruits in software engineering field. It terminated the fighting in the field of modeling language of object oriented technology. But how to use UML to solve the real world problem is still the hot topic on the field. From the view of the requirements for software development, the flexible software development process is presented to fit the changing world, and the framework of integrated UML software development environment is designed to support modeling, simulation and round trip development. The environment should be composed of UML visual modeling system,UML simulation system,UML code generation system and UML reverse translation system.

从当前对软件工程过程的需求出发,结合软件工程领域的最新成果统一建模语言UML(UnifiedModelingLanguage),重点讨论了适应需求变化的迭代式软件开发过程,提出了柔性软件开发模型.在此研究的基础上,设计了集成化UML软件开发环境的框架,指出其组成应包括UML可视化建模系统、UML模拟系统、UML代码生成系统和UML逆向变换系统4个部分,并提出了需要解决的问题.

Leukemia inhibitory factor (LIF) can maintain embryonic stem cell monolayers in a pluripoent undifferntiated state, thus function at blastocyst implantion and influence on early embryonic divelopment in mice. It has been reported that the expression of LIF should be highly time-dependent. This study conducted on the endometria of mice to check the expression of LIF by reverse translation-Polymerase chain reaction(RT-PCR).

Leukemia inhibitory factor (LIF) can maintain embryonic stem cell monolayers in a pluripoent undifferntiated state, thus function at blastocyst implantion and influence on early embryonic divelopment in mice. It has been reported that the expression of LIF should be highly time-dependent. This study conducted on the endometria of mice to check the expression of LIF by reverse translation-Polymerase chain reaction(RT-PCR). The results showed that the samples from the endometna of 4th day-pregnancy mice produced a clear electrophoresis band at 538 bp on the electropherogeram, which indicated that LIH expression was carried out in this issue. But no expression of LIF was found in all samples from the endometria of 13 nonparegnancy mice. It was discussed in this paper that there was a close correlation of the expression of gene LIF in endometrium with level progestogen at different estrus cyclin mice, an suggested that a sufficient level of progestogen might play a crucial role in promoting the expression of LIF.

白血病抑制因子(LIF)能抑制胚胎干细胞的分化和保持其增殖能力,并与胚泡着床及胚胎早期发育有着密切的关系。经实验证实,LIF基因在子宫内膜中的表达具有高度的时间限制性。采用反转录聚合酶链式反应技术(RT-RCR)对小鼠子宫内膜LIF基因表达进行了研究,结果显示:妊娠第4天小鼠的子宫内膜组织的样本在电泳图的538bp处出现清晰的电泳带,表明该组织有LIF基因的强表达;而在所检测的13只非妊娠小鼠子宫内膜的组织样本中均未发现LIF基因表达讨论了小鼠动情周期中各阶段的孕激素水平对子宫内膜LIF基因表达产生的影响,提出了一定的孕激素水平是启动LIF基因表达的必要条件
