77. The technique known as yeast two hybrid analysis for detecting interacting gene products depend on:
(A) activation of DNA polymerase by the nearby binding of hybridizing protein complexes.
(B) direct binding of a Gal4p activation domain to a DNA sequence in the promoter region.
(C) having a promoter that responds directly to one of the two proteins whose interactions is beingmeasured.
(D) hybridization of DNA segments corresponding to the two genes being examined.
(E) stimulation of transcription by interaction of two Gal4p domains via fused protein sequences.
