从反义RNA到RNA干扰:科学突破的机遇与创新

RNA干扰是近年发现的存在于真核细胞内的一种重要防御机制,现已发展成为一种全新的基因阻断技术,广泛用于抗病毒、抗肿瘤和后基因组时代基因功能研究.它是在反义RNA研究中意外获得的重大科学突破,其发现过程对科学研究有重要启示意义.     

是RNA创建了生物界

本文首先重提复制原理,其次又归纳了其构筑单体须经选择的聚合物制造法则,从而能证明是ＲＮＡ有创建生物界的能力。本文后半部分列出了ＲＮＡ创建历程的纲要：生物诞生、各种ＲＮＡ入股自复制集团、基因组形成并取得信息独立地位、双链ＤＮＡ成为基因组存在的绝对优势形式、程序性调控周期形成的必然性     

RNA干扰现象研究获诺贝尔奖的启示

RNA干扰现象是目前生命科学领域的研究热点。由于RNA干扰具有十分重要的理论和应用价值,因此该现象在揭示后仅8年其研究者就获得了诺贝尔生理与医学奖。通过回顾RNA干扰现象的发现历程,可以为今后的科研探索过程提供许多有益的启示。     

THE GENETIC RECOMBINATION OF SCIENCE AND RELIGION

The estrangement between genetic scientists and theologians originating in the 1960s is reflected in novel combinations of human thought (subject) and genes (investigational object), paralleling each other through the universal process known in chaos theory as self‐similarity. The clash and recombination of genes and knowledge captures what Philip Hefner refers to as irony, one of four voices he suggests transmit the knowledge and arguments of the religion‐and‐science debate. When viewed along a tangent connecting irony to leadership, journal dissemination, and the activities of the “public intellectual” and the public at large, the sequence of voices is shown to resemble the passage of genetic information from DNA to mRNA, tRNA, and protein, and from cell nucleus to surrounding environment. In this light, Hefner's inquiry into the voices of Zygon is bound up with the very subject matter Zygon covers.     

RNA生命起源学说的佐证与思考

ＤＮＡ、ＲＮＡ和蛋白质是组成生物体的重要的生物大分子，但关于何者是生命的起源，至今众说纷纭。近来的研究表明，ＲＮＡ可能是生命的起源。本文简述了有关此学说的一些主要证据，并就其中的一些问题进行了讨论。     

The RNA World and Divine Action in and Through Quantum Mechanics

ABSTRACT

Life emerged on Earth approximately 4.1 billion years ago. Current scholarship on the origin of life supports the RNA world scenario, although controversy still goes on. This article examines the origin issue in light of a divine action theory proposed by Robert J. Russell. Although the author himself has not much considered the issue in light of the divine action, the article is still fruitful in the sense that the origin of life issue is now incorporated into the dialogue with divine action, and also that Russell’s divine action theory can be reconsidered in a new context.
