Polycomb group (PcG) mutants cause gain-of-function of Antennapedia (Antp) and other homeotic genes by causing some of these genes to be expressed in tissues where they are usually repressed. PcG has a domain that binds to methylated histone H3
This finding supports which of the following hypotheses? A) that PcG binds to Antp genes and serves as a transcription activator B) that PcG mutants have phenotypes like those of Antp mutants C) that PcG regulates genes by altering chromatin remodeling D) that PcG initiates repression of Antp genes in tissues E) that PcG is a repressor molecule like those found in bacteria
