Reorder the following

• DNA unwinds & separates to 2 strands using the enzyme helicase

• Each new strand is complementary to the template strand.

• 2 new strands rezip forming 2 identical strands of DNA

• The polymerase enzyme adds new nucleotides to the template strand.

Select the parent, or original strand.
