Could you please provide a breakdown of how DNA and protein separation are different in gel electrophoresis, i.e. how DNA vs proteins are being separated. This is what I got from the MCAT textbook but I'm getting different answers online, for example some sources say that protein can be separated by size as well. Please clarify.
i. Nucleic acids separated by size of particles
ii. Proteins separated by charge, length, isolelectric point, and weight
