The effect of temperature and primer concentration on oligonucleotide-primed transcription has been studied using the separated strands of a well-defined natural DNA as template. Results were similar to those obtained in the homopolymer-directed model systems. At high temperature and excess primer concentration mainly primer-initiated RNA copies are synthesized. Omission of one ribonucleoside triphosphate also makes the termination specific. The unique RNA fragments thus obtained have been used to determine the perfectly-repeated sequence of 68 base pairs in this DNA.
利用一条明确的天然DNA的单链作为模板,研究了温度和引物浓度对寡核苷酸引发转录的影响。结果与在均聚物导向模型系统中获得的结果相似。在高温和过量引物浓度下,主要合成引物起始的RNA拷贝。省略一种核糖核苷三磷酸也会使终止具有特异性。由此获得的独特RNA片段已被用于确定该DNA中68个碱基对的完全重复序列。
