摘要

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.
