What: "If the genome is like a genetic cookbook filled with recipes for making all of the cells in a plant or animal, the process known as methylation is like a series of paperclips pinning certain pages together to render those recipes unreadable.Methylation tailors gene expression, allowing every cell in the organism to carry all the recipes, but permitting access only to the instructions each specific cell type needs."
