A Protein-Protein Interaction Is Responsible for an Illness in Infants

A protein-protein interaction is responsible for an illness in infants. The most accurate mechanisms used to assess the proteins involved include

A) Isolation of the DNA sequence for the genes encoding the proteins.
B) Insertion of the genes encoding the proteins into yeast using bait and prey vectors.
C) Addition of fusion proteins from the infants to yeast to induce a color change response.
D) The identification of active protein interactions by the expression of reporter genes.
