    • This invention provides inter alia an in vitro process for producing multiple specific nucleic acid copies in which the copies are produced under isostatic conditions, e.g., temperature, buffer and ionic strength, and independently of any requirement for introducing an intermediate structure for producing the copies. In other aspects, the invention provides in vitro processes for producing multiple specific nucleic acid copies in which the products are substantially free of any primer-coded sequences, such sequences having been substantially or all removed from the product to regenerate a primer binding site, thereby allowing new priming events to occur and multiple nucleic acid copies to be produced. This invention further provides a promoter-independent non-naturally occurring nucleic acid construct that produces a nucleic acid copy or copies without using or relying on any gene product that may be coded by the nucleic acid construct. Another aspect of this invention concerns a protein-nucleic acid construct in the form of a conjugate linked variously, e.g., covalent linkage, complementary nucleic acid base-pairing, nucleic acid binding proteins, or ligand receptor binding. Further disclosed in this invention is an in vivo process for producing a specific nucleic acid in which such a protein-nucleic acid construct conjugate is introduced into a cell. A still further aspect of the invention relates to a construct comprising a host promoter, second promoter and DNA sequence uniquely located on the construct. The host transcribes a sequence in the construct coding for a different RNA polymerase which after translation is capable of recognizing its cognate promoter and transcribing from a DNA sequence of interest in the construct with the cognate promoter oriented such that it does not promote transcription from the construct of the different. RNA polymerase.
    • 本发明特别提供用于生产多种特异性核酸拷贝的体外方法,其中拷贝在等静压条件下,例如温度,缓冲液和离子强度下产生,并且独立于引入用于产生拷贝的中间结构的任何要求。 在其它方面,本发明提供了用于产生多种特异性核酸拷贝的体外方法,其中产物基本上不含任何引物编码的序列,这些序列基本上或全部从产物中除去以再生引物结合位点,从而 允许发生新的引发事件并产生多个核酸拷贝。 本发明进一步提供了一种与天然存在的启动子相关的非天然存在的核酸构建体,其不使用或依赖于可由核酸构建体编码的任何基因产物产生核酸拷贝或拷贝。 本发明的另一方面涉及以不同方式连接的缀合物形式的蛋白质 - 核酸构建体,例如共价连接,互补核酸碱基配对,核酸结合蛋白或配体受体结合。 在本发明中进一步公开的是用于生产其中将这种蛋白质 - 核酸构建体缀合物引入细胞的特异性核酸的体内方法。 本发明的另一方面涉及包含宿主启动子,第二启动子和唯一位于构建体上的DNA序列的构建体。 宿主转录编码不同RNA聚合酶的构建体中的序列,其在翻译后能够识别其同源启动子并且从构建体中感兴趣的DNA序列转录成同源启动子定向,使得其不促进构建体的转录 的不同。 RNA聚合酶。
