How does the process of gel electrophoresis produce DNA fingerprints? An electric current sorts DNA nucleotides according to their bases. O An electric current cuts a DNA strand into segments of various lengths O An electric current causes segments of DNA to move at different rates O An electric current supplies a charge to uncharged segments of DNA
