Can one transcription factor sometimes act as a repressor and sometimes act as an activator?
a. Yes, but it depends on where the transcription factor binds in the promoter
b. Yes, but it depends on other proteins that might act with the transcription factor
c. No, transcription factors are always either activators or repressors
d. Yes, but only if a mutation happens
