WebThis allows computing damage patterns from sequence libraries of mammalian nuclear DNA in which damage has been repaired, e.g. using uracil–DNA–glycosylase and endonuclease VIII. This is done by restricting to nucleotides in a CpG context, for which deamination of methylated Cytosine results in Thymine. WebIt has been known for a long time that deamination of adenine 1, guanine 2, and cytosine 3 (Scheme 1) results in the formation of hypoxanthine, xanthine, and uracil, respectively, and these ...
