What is the principle of electrophoresis?
Molecules are separated based on their size and structure
Molecules are separated based on their charge and viscosity of the solution
Molecules are separated based on their size and charge
Molecules are separated based on their weight and porosity of the gel
The migration of a charged molecule in an electric field is directly proportional to the molecule's charge and the viscosity of the solution
Each molecule must have specific charge and size and migrate to a single position in an electric field within a given time interval
In a mixture of ions (such as proteins), each one must position itself in a unique place within the electric field
The separation occurs according to the size and structure of the molecules (molecular sieving)
a) 1 and 2 are correct.
b) 2 and 3 are correct.
c) 3 and 4 are correct.
d) 1 and 3 are correct.
