What are some similarities and differences between electropheresis and paper chromotagraphy?

Answer 1

The similarity is the fact that both processes separate molecules and compounds. However, paper chromatography separates by polarity (normally) and electrophoresis separates by electronegativity.

Answer 2

Both methods are used to separate compounds in a mixture. Paper chromatography works with small molecules and is based on the solubility of the compounds in a particular solvent. Gel electrophoresis works with large molecules like proteins and DNA fragments based on the differences of charges in the molecules.

Answer 3

The main similarity is that some molecules are carried farther along than other molecules during the same time period. So the different molecules are separated during the process.
