試題詳解

31. The technique known as yeast two hybrid analysis for detecting interacting gene products depends on:
(A) Stimulation of transcription by interaction oftwo Gal4p domains via fused protein sequences.
(B) Direct binding of a Gal4p activation domain to a DNA sequence in the promoter region.
(C) Havinga promoter that responds directly to one of the two proteins whose interactions are being measured.
(D) Hybridization of DNA segments corresponding to the two genes being examined.
(E) Activation of DNA polymerase by the nearby binding of hybridizing protein complexes.
