General Transcription Factors and RNA Polymerase Assemble into the Basal

Multiple Choice

General transcription factors and RNA polymerase assemble into the basal transcription apparatus, which binds to DNA near the start site and is necessary for transcription to take place at minimal levels. Additional proteins called transcriptional activators bind to other consensus sequences in promoters and enhancers and affect the rate of transcription.
-What is the difference between the core promoter and the regulatory promoter?

A) Only the core promoter has consensus sequences.
B) The regulatory promoter is farther upstream of the gene.
C) Transcription factors bind to the core promoter; transcriptional activator proteins bind to the regulatory promoter.
D) Both b and c.
