The cell needs to be destroyed by an outside modality or by the body,” she explains.
What is UV endonuclease?
Excision endonuclease, also known as excinuclease or UV-specific endonuclease, is a nuclease (enzyme) which excises a fragment of nucleotides during DNA repair. The excinuclease cuts out a fragment by hydrolyzing two phosphodiester bonds, one on either side of the lesion in the DNA.
