When electrophoretic separations are done based on molecular weight, the distance that a molecule moves can be graphed as a straight line when compared to:
A) the MW of the proteins
B) the negative of the MW of the proteins
C) the log of the MW of the proteins
D) none of these

Question

Quizplus · Accepted Answer

The distance that a molecule moves during electrophoretic separations based on molecular weight can be graphed as a straight line when compared to the log of the molecular weight (MW) of the proteins. This is because the relationship between the log of the molecular weight and the migration distance is linear.
