Epigenetic signals help determine which genes are activated at which time in a given cell. A novel analytical method enables systematic characterization of the relevant epigenetic tags, and reveals that the system adapts to the loss of single epigenetic writer and eraser enzymes. With a few exceptions, every cell type in a multicellular organism carries the same endowment of genetic instructions encoded in the nucleotide … Continue reading Scientists begin to hone Precision Epigenetics.
