Many transcriptional activators are proteins with a DNA -binding domain (DBD) and an activation domain (AD). a. True
b. False

True

Explanation:

Transcriptional activators are proteins that contain domains and/or motifs that bind to DNA in order to induce transcription of specific nearby genes. In general, transcriptional activators enhance the binding with the RNA polymerase complex in order to start transcription. The DNA-binding domains (DBDs) are protein domains that enable a transcriptional activator the binding with enhancers or promoter-proximal elements. Some examples of DBDs include the zinc finger domain, helix-turn-helix domain, leucine zipper domain, etc. On the other hand, the activation domains (ADs) such as, for example, C-terminal activation domains, enable the interaction of the transcriptional activator with coactivators during the formation of the preinitiation complex, thereby transmitting the activating signal to the transcription machinery.

this website is for anybody really not just for girls just saying, also while a lot of males are mean and you know there are the few who are kind and then there's the nice-guys but then theirs also guys like me who are shy we don't get out much because there are people like you who exist who would most likely punch a guy in the face so next time just think about things before you post them to a website where guys and girls can see your question.
