genomic sequencing

[Alex Dobrovic]

In all the dicussion of genomic sequencing, it seems to have been
overlooked that this method can determine whether the cytosines are
methylated. The method that is now generally used utilizes
bisulfite-induced modification of genomic DNA and strand specific PCR. It
was developed by Marianne Frommer and more recently improved by Sue Clarke.
