From: BSMAP: whole genome bisulfite sequence MAPping program
Pipeline of bisulfite sequencing. 1) Denaturation: separating Watson and Crick strands; 2) Bisulfite treatment: converting un-methylated cytosines (blue) to uracils; methylated cytosines (red) remain unchanged; 3) PCR amplification of bisulfite-treated sequences resulting in four distinct strands: Bisulfite Watson (BSW), bisulfite Crick (BSC), reverse complement of BSW (BSWR), and reverse complement of BSC (BSCR).
