If a protein repression complex contained a faulty enzyme that could no longer remove acetyl groups from histones, the most likely outcome would be that
A) gene expression would decrease because RNA polymerase would be unable to bind to the promoter region.
B) gene expression would neither increase nor decrease because the acetylation of histones is not involved in the regulation of gene expression.
C) DNA would not be able to be expressed because of the formation of tightly bound nucleosomes.
D) the protein repressor complex would be degraded by endonucleases.
E) gene expression would become constitutive.
