This complex now forms a dimer that can bind the activator d. hormone binds to its receptor. This complex now forms a dimer that can bind the enhancer element e. a and d are correct 58. Repression of eukaryotic transcription occurs when: a. a repressor and activator compete for the binding of the same enhancer sequence b. a repressor binds to and blocks the enhancer-binding domain of an activator c. a repressor binds the promoter region and prevents the basal factors from binding d. both a and b e. all of the above 59. Which of the following is true regarding epigenetic changes? a. the methylation that occurs subsequently changes the nucleotide sequence b. can change gene expression without a change in nucleotide sequence c. can not be passed on or inherited by offspring d. can only be inherited and cannot develop in an individuals lifetime e. all of the above 60.
