The influence of Rous sarcoma virus (RSV)-associated RNase H on the in vitro synthesis of DNA by the RSV RNA-directed DNA polymerase was determined under conditions whereby RNase H activity was selectively inhibited with NaF. Not only were we unable to detect any effect on the size, structure, or genetic complixity of the DNA product synthesized in the absence of RNase H activity, but the displacement of DNA from the 70S RNA:DNA hybrid structures was also unaffected. The suitability of 70S RNA:DNA hybrid structures synthesized in vitro to serve as a substrate for RNase H is discussed.
在通过氟化钠选择性抑制核糖核酸酶H活性的条件下,测定了劳氏肉瘤病毒(RSV)相关核糖核酸酶H对RSV RNA指导的DNA聚合酶体外合成DNA的影响。我们不仅未能检测到在不存在核糖核酸酶H活性的情况下合成的DNA产物在大小、结构或遗传复杂性方面受到任何影响,而且从70S RNA:DNA杂交结构中置换DNA的过程也未受影响。本文讨论了体外合成的70S RNA:DNA杂交结构作为核糖核酸酶H底物的适用性。
