Bisulfite Sequencing
Bisulfite sequencing is a molecular biology technique used to detect DNA methylation patterns at single-nucleotide resolution. It involves treating DNA with sodium bisulfite, which converts unmethylated cytosines to uracils while leaving methylated cytosines unchanged, followed by sequencing to map methylation sites across the genome. This method is crucial for studying epigenetic regulation in fields like cancer research, developmental biology, and genomics.
Developers should learn bisulfite sequencing when working in bioinformatics, computational biology, or genomics to analyze epigenetic data, as it's the gold standard for DNA methylation profiling. It's essential for projects involving disease biomarker discovery, understanding gene expression regulation, or integrating methylation data with other omics datasets. Use cases include processing raw sequencing reads, aligning bisulfite-treated sequences, and performing differential methylation analysis in tools like Bismark or MethylKit.
