Subsequently, it has been shown that RISC contains at least one member of the argonaute protein family, which is likely to act as an endonuclease and cut the mRNA (nowadays often referred to as the Slicer function).
Double-stranded RNA is cut into short pieces (siRNA) by the endonuclease Dicer.
AP endonuclease recognizes this site and nicks the damaged DNA on the 5 'side (upstream) of the AP site creating a free 3'-OH.

This was an exciting period in the molecular biology of adenovirus with the discoveries (a) that only one specific fragment of the genome, the E1 region, was responsible for oncogenic transformation; (b) that restriction endonuclease length polymorphism could be utilized to generate genetic maps; (c) the mapping of specific genes on the viral genome; and (d) generation of a viral map of sequences expressed as stable RNAs.
Ulf, I, and others generated the first restriction endonuclease maps of this virus, and Dr.S. Jane Flint and I began to analyze the regions of the genome expressed as mRNAs in both productively infected cells and in adenovirus transformed cells.

Hamilton Smith telling me about the restriction endonuclease he had discovered in Hemophilus influenzae aroused my interest in the possibility of using restriction enzymes to dissect the genomes of DNA tumor viruses.
The chemistry of water activated by a magnesium ion is central to the function of the DNA repair proteins, apurinic/apyrimidic endonuclease 1 (Ape1) and polymerase A (Pol A).
