RNase H,即Ribonuclease H,中文名为核糖核酸酶H,是一种核糖核酸内切酶,可以特异性地水解DNA-RNA杂合链中的RNA。RNase H不能水解单链或双链DNA或RNA中的磷酸二酯键,即不能消化单链或双链DNA或RNA。
特点:特异性消化DNA-RNA杂合链中的RNA,常用于cDNA第二链的合成。
用途:DNA-RNA杂合链中去除RNA,例如cDNA第二条链合成前去除mRNA;通过互补的DNA序列实现对RNA的定点剪切;除去杂交到poly(dT)上的mRNA中的poly(A);体外多腺苷酸化反应(polyadenylation reaction)产物研究。

文献和实验RNase H: Specificity, Mechanisms of Action, and Antiviral Target
The Ribonuclease (RNase) H is one of the four enzymes encoded by all retroviruses, including HIV. Its main activity is the hydrolysis of the RNA moiety in RNA–DNA hybrids. The RNase H ribonuclease is essential in the retroviral life cycle

scaffold, using RNase H and two DNA oligonucleotides. After cleavage, we show that the RNA of interest can be isolated in a one-step purification. This method has, in particular, applications in structural investigations of RNA.
Question 1.What are the differences among RNase H, RNase A, RNase B and RNase C? 2.In your cDNA kits, RNase H is added in the second strand reaction to produce more nicked RNA as primers for DNA synthesis. In this repect
