Put the following steps of the mismatch repair mechanism in order.
I. MutS and MutL form a complex at the site of the mismatch and form a loop while scanning in both directions along the DNA.
II. Mismatched bases are recognized by MutS.
III. When the MutS-MutL complex finds a GATC site, MutH binds to the complex and cleaves the unmethylated strand.
IV. Helicase and exonuclease activities unwind and degrade the strand containing the mismatched base.
V. Pol III fills the gap and ligase seals the DNA strand.

II, I, III, V, IV
