Which of the following describes the process seen in the image above?

A

The “TATA” box is used as a signal for the termination of transcription.

B

The enhancer region is upstream from the binding site of RNA polymerase, which allows transcription factors to bind and initiate transcription.

C

The enhancer region acts to loop up DNA and therefore silence gene expression.

D

The “TATA” region of the DNA is known as the promoter, which signals DNA polymerase to start transcribing.
