abstract：:Oxanine (O) is a deamination product derived from guanine with the nitrogen at the N1 position substituted by oxygen. Cytosine, thymine, adenine, guanine as well as oxanine itself can be incorporated by Klenow Fragment to pair with oxanine in a DNA template with similar efficiency, indicating that oxanine in DNA may c...
