Basically, it goes something like this...

  • The DNA helix unwinds
  • DNA helicase breaks the hydrogen bonds betweent the bases which leaves two strands of DNA
  • Free nucleotides pair up with each of the bases on the strands
  • DNA polymerase joins the free nucleotides to the original strands using complemntory base pairing
  • This creates two identical strands of DNA

Theres an animated version which explains it here> http://www.youtube.com/watch?v=zdDkiRw1PdU&feature=related

Hope this helped :)
