Recent research shows that genomic DNA is highly methylated in normal cells, except the GC-rich reach regions. In contrast, cancer cells are highly methylated in their GC-rich genomic regions as well, but lamin-bound DNA becomes de-methylated in cancer cells. The initial DNA expression differences in normal and cancer cells are attributed to the differences in their DNA methylation levels. This is an example of which of the following?
