Definition of Charge-based migration in an electric field
Check what you remember
Read the wording for your board, then hide it and explain Charge-based migration in an electric field in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
Nucleic acids carry negative phosphate groups, so they migrate towards the positive electrode; proteins are given a uniform negative charge by SDS, so they too move towards the positive electrode.
