RNase H is the enzyme that recognizes and degrades the RNA strand of RNA-DNA duplexes, which is a crucial step in the process of cDNA cloning.  RNase H recognizes RNA-DNA duplexes and randomly cleaves the phosphodiester backbone of the RNA. The enzyme is primarily used to cleave the mRNA strand that is annealed to the first strand of cDNA generated by reverse transcription.
