The main way to sequence DNA methylation. Converts methylated cytosine to uracil, and then we can sequence those.

Bisulfite sequencing is a method used to determine the methylation status of DNA, particularly focusing on the conversion of cytosine residues in DNA. This technique exploits the unique properties of sodium bisulfite, which converts unmethylated cytosines into uracils (which are subsequently treated as thymidines during PCR amplification), while leaving methylated cytosines unchanged.
