How does electrophoresis work?

What do you know about amino acids in different pH?

Prince Umair,

Its probably worth refamiliarising yourself with amino acid structure and in particular how the carboxylic acid and amine groups act with varying pH. Have a look at the following link and this should give a nice explanation of amino acid behaviour and should help you answer your question.

Kind Regards
