- 5-Methylcytosine is the most common covalently modified base in the DNA of eukaryotic cells. For example, it plays a role in the regulation of transcription, in genetic imprinting and in tumorigenesis. Identification of 5-methylcytosine as an ingredient genetic information is therefore of considerable interest. However, 5-methylcytosine positions cannot be identified by sequencing because 5-methylcytosine has the same base pairing behavior as cytosine. In addition, a PCR
- Methylcytosine is based on the specific reaction of bisulfite with cytosine, which after subsequent alkaline hydrolysis is converted into uracil, which corresponds in its base pairing behavior to thymidine. 5-Methylcytosine, however, is not modified under these conditions. The original DNA is thus converted in such a way that methylcytosine, which originally cannot be distinguished from the cytosine by its hybridization behavior, can now be detected by "normal" molecular biological techniques as the only remaining cytosine, for example by amplification and hybridization or sequencing.
