A gene that had been turned off in a liver cell has just been induced to be highly expressed as the cell responds to a new metabolic load. What observations do you expect to accompany this change?

A) More than 100 proteins would become associated with the gene for its transcription.
B) The nuclear position of the gene would change to place it in a "transcription factory."
C) Chromatin modifications associated with the gene would change in favor of higher expression.
D) All of the above.
