The movement of DNA or RNA in gel electrophoresis is often a matter of molecular weight alone. Which of the following molecular parameters usually influence the movement of protein?

a. weight, charge, or shape
b. only charge
c. only shape
d. only weight and shape
d. only weight

Gel electrophoresis is a molecular technique used to separate samples of DNA, RNA and proteins on the basis of charge, mass or size. The molecules migrate through a gel matrix supplied with electric current on the basis of size or charge. For example, +ve charge molecules move towards the -ve end of the matrix or smaller molecules move faster.

According to this question, the movement of DNA or RNA in gel electrophoresis is often a matter of molecular weight (size) alone. However, that of protein involves a combination of weight, charge, or shape.
