Which of the following is true of the structure of typical transcriptional activators?

a. they contain only one type of motif.
b. the regulatory domain contains the dna-binding motif.
c. the dna-binding domain always binds to the coactivator.
d. they contain a regulatory domain that is functional when removed from the dna-binding domain.

D.They contain a regulatory domain that is functional when removed from the DNA-binding domain.

Explanation:

Transcriptional activators are transcriptional factors that positively regulate transcription of the gene (increase gene transcription). They usually contain two functional domains:

Mechanism of action of activators includes their binding to the enhancers (DNA sequences) and recruitment of RNA polymerase II to the promoter.

frogs. the lower the ph the higher the acid content. frogs have the highest tolerance in this scenario.
