Which of the following are true regarding SDS-PAGE? (Check all that apply) O Without SDS, polypeptide migration in the gel would be influenced by the intrinsic charge due to the amino acid side chains O SDS disrupts secondary and tertiary structure of polypeptide chains O Without SDS, polypeptide migration in the gel would be influenced by the intrinsic charge of the polypeptide backbone O SDS coats polypeptide chains with an electrical charge so that they move toward the negative electrode during electrophoresis O In the presence of SDS, polypeptide migration in the gel is determined by size (or mass). SDS disrupts covalent bonds between polypeptide chains O.
