Methylation changes in DNA alter gene production and/or expression. Here is an enzyme that removes methylation to prepare for other epigenetic changes.:-"The finding is important for the field of epigenetics because Tet enzymes chemically modify DNA, changing signposts that tell the cell's machinery "this gene is shut off" into other signs that say "ready for a change."
 
"Tet enzymes' roles have come to light only in the last five years; they are needed for stem cells to maintain their multipotent state, and are involved in early embryonic and brain development and in cancer."-
