Question

Which of the following sequences can be found in the core promoter of RNA polymerase II? Select all that apply.

A. InrB. BREC. EnhancerD. DPE

Answer 1

A. Inr, B. BRE, D. DPE

Step-by-step explanation:

Core promoter of RNA polymerase II is a sequence of DNA that initiates transcription (contains the transcription start sites). Core promoter is usually 60 to 120 base pairs and in its structure it contains a binding site for RNA polymerase and also structural motifs such as Inr, BRE, DPE, TATA box etc. involved in the regulation of transcription (e.g. binding of enhancers).
