Protein-protein interactions are studied by: P. DNA foot printing Q. Yeast two hybrid system R. Ligase chain reaction S. Mass spectrometry Options: (A) P and S only (B) Q and S only (C) P and R only (D) Q and R only
Protein-protein interactions are studied by:
P. DNA foot printing
Q. Yeast two hybrid system
R. Ligase chain reaction
S. Mass spectrometry
Options:
(A) P and S only
(B) Q and S only
(C) P and R only
(D) Q and R only
Answer
Answer: (B) Q and S only
Explanation: Yeast two hybrid system (Q) and mass spectrometry (S) are methods used to study protein-protein interactions. DNA foot printing (P) is used to study protein-DNA interactions, and ligase chain reaction (R) is not typically used for studying protein-protein interactions.
