Answer:
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:
- DNA-binding domain which interacts with DNA
- Activation domain which interacts with other proteins.
Mechanism of action of activators includes their binding to the enhancers (DNA sequences) and recruitment of RNA polymerase II to the promoter.
Answer:
