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.
Excision endonuclease, also known as excinuclease or UV-specific endonuclease, is a type of nuclease that removes a section of nucleotides during DNA repair by cutting two phosphodiester bonds on either side of a lesion in the DNA.
