B) the same sedimentation coefficient.
C) the same diffusion coefficient.
D) the same conformation.
E) none of the above

Quizplus · Accepted Answer

Molecular weight is only one characteristic of a protein, and it is possible for two proteins to have the same molecular weight but differ in other properties such as amino acid composition, sedimentation coefficient, diffusion coefficient or conformation. Therefore, option E is the correct choice.
