WebDNase DNases, or deoxyribonucleases, are enzymes that specifically cleave and degrade DNA. In molecular biology, DNase (namely DNase I) is used to degrade DNA in applications such as RNA isolation, reverse transcription preparation, DNA-protein interactions, cell culture, and DNA fragmentation.

WebEC 3.1.26.4: RNase H is a ribonuclease that cleaves the RNA in a DNA/RNA duplex to produce ssDNA. RNase H is a non-specific endonuclease and catalyzes the cleavage of RNA via a hydrolytic mechanism, aided by an enzyme-bound divalent metal ion. RNase H leaves a 5'-phosphorylated product.
