Function of ribonuclease
WebRNase H is found in both the nucleus and the cytoplasm of all cells [74]. Its regular function is to remove RNA primers from Okazaki fragments during DNA replication. Hence, oligonucleotides that act via RNase H activation must be designed carefully.

Did you know?
WebThe human ribonuclease A (hRNase A) superfamily is comprised of 13 members of secretory RNases, most of which are recognized as catabolic enzymes for their ribonucleolytic activity to degrade ribonucleic acids (RNAs) in the extracellular space, where they play a role in innate host defense and physiological homeostasis. WebRNases, which play important roles in nucleic acid metabolism, are found in both prokaryotes and eukaryotes, and in practically every cell type. The human body uses RNases to defend against invading microorganisms …
