In the ribonuclease experiments performed by Anfinsen, β-mercaptoethanol reduced:
a all bonds, and the unfolded protein molecules became tangled up with one another to form aggregates.
b incorrectly paired disulfide bonds, allowing them to reform with the correct pairing until the most stable conformation of the protein had been obtained.
c all incorrectly paired bonds and stabilized the protein structure.
d all bonds and destroyed the protein structure.
