Unwinding and Rewinding: Double Faces of Helicase?

<table>A model of helicase function to unwind or rewind double-stranded nucleic acid. Note that helicase (oval) represents both translocation polarities; either ATP-dependent or ATP-independent for strand annealing activity has been observed in helicases (see Table <a href="../tab1/">1</a>).</table>
