Description

Ribonuclease H (RNase H) is an endonuclease that specifically hydrolyzes the phosphodiester bonds of RNA hybridized to DNA to produce 3′-OH and 5′-P-terminated products. It will not degrade single-stranded nucleic acids, double-stranded DNA or double-stranded RNA. This endonuclease can be used in applications such as microarrays.
