How to "duplicate" an element using jQuery?

Question

Possible duplicate:
Is it possible to clone html element objects in JavaScript / jQuery?

For example, I want:

<div id="foo1"> </div> <div id="foo2"> <div>Foo Here</div> </div> 

To become the following:

 <div id="foo1"> <div>Foo Here</div> </div> <div id="foo2"> <div>Foo Here</div> </div> 

Is this possible with jQuery?
