Successful Cotransformation in the Yeast Two-Hybrid System Will Result in the Binding

Multiple Choice

Successful cotransformation in the yeast two-hybrid system will result in the binding of proteins produced by each yeast expression vector. These fusion proteins function by

A) binding to the lacZ operator, preventing transcription.
B) binding to the lacZ repressor, enabling transcription.
C) changing color in the presence of X-gal.
D) binding to RNA polymerase, preventing transcription.
