The first detailed molecular structure of a member of the Tet family of enzymes is being obtained by scientists. 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 ...Thursday, 26 December 2013
