Explanation / Answer

Glu ,Asp are negatively charged at pH 7, so migrate to Anode

In Ser-Asp, COOH group of Asp is free and negatively charged, so this peptide moves to anode.

Lys, Arg are positively charged so migrate to cathode

In His-Lys NH2 group of His is free , and it is positively charged..So migrate to cathode.

All remaining amino acids and peptide donot move.

(You made mistake in choosing the charge of cathode anode...Anode is positively charged, so species having negative charge move to anode)
