Best Answer

The DNA has a structure called a Double Helix which is then "unzipped" by different enzymes which leaves 2 strands.

The DNA strands serves as a template for a new strand as once the strands are translated so like coding for DNA. ATGCGTATA is translated to TACGCATAT then the strand is then built so that you are left with 2 identical DNA molecules.
