Bisulfite Sequencing - detect DNA Methylation - YouTube
Bisulfite sequencing is used widely across mammalian genomes, however complications have arisen with the discovery of a new mammalian DNA modification 5-hydroxymethylcytosine. 5-Hydroxymethylcytosine converts to cytosine-5-methylsulfonate upon bisulfite treatment, which then reads as a C when sequenced. Therefore, bisulfite sequencing cannot discriminate between 5-methylcytosine and 5-hydroxymethylcytosine. This means that the output from bisulfite seque… WebWhat does bisulfite conversion do? Bisulfite Conversion is a process in which genomic DNA is denatured (made single-stranded) and treated with sodium bisulfite, leading to deamination of unmethylated cytosines into uracils, while methylated cytosines (both 5-methylcytosine and 5-hydroxymethylcytosine) remain unchanged. WebIn bisulfite conversion, DNA is first denatured so that it is single stranded. The addition of sodium bisulfite will sulfonate unmethylated cytosines at a low pH, which then undergo spontaneous deamination into sulfonated uracil molecules, and subsequent desulfonation results in uracil molecules [28]. kandy best food places
