Chromatin Immunoprecipitation (ChIP) is same as Chromosome Conformation Capture.

3C assays involve three basic steps:

(1) interacting chromosome segments are cross-linked with formaldehyde, 

(2) the DNA is digested, and

(3) cross-linked DNA fragments are ligated to produce products that are amplified and can be further analyzed.

Adenine and guanine are also subject to spontaneous deamination. Deamination converts adenine to hypoxanthine, which hydrogen-bonds to cytosine rather than to thymine; guanine is converted to xanthine,

which continues to pair with cytosine, although with only two hydrogen bonds.
