摘要：
How can the same gene remember that it is 'off' in one cell lineage and 'on' in another? Studies of how homeotic genes are regulated in Drosophila melanogaster have uncovered a transcriptional maintenance system, encoded by the Polycomb and trithorax group genes, that preserves expression patterns across development. Here we try to formulate a broad framework for the types of molecular mechanism used by the Polycomb and trithorax proteins.
