38. All are true for transcription activation except:
(A) takes place when a transcriptional activator protein bound to DNA makes protein : protein contacts with RNA polymerase.
(B) the degree of transcriptional activation is proportional to the strength of the protein : protein interaction.
(C) a nucleotide sequence binding site for a DNA-binding protein serves as an activator site if DNA-binding protein can interact with promoter-bound RNA polymerase.
(D) if the DNA-bound transcriptional activator makes contact with two different components of RNA polymerase, the transcription is markedly elevated.
(E) All are true.
