DNA has two "strands" which in the zipper analogy serve as the two sides of your zipper. In the middle extending towards each other are bases, that act like the "teeth of the zipper. The bases on one strand stick to the bases on the other strand.
The two strands can be pulled apart and put back together just like a zipper.

The DNA molecule incorporates a double helix shape. With 2 Strands and a sequence of connection between them. while this molecule uncoils and seperate, they do as though a zip. the two the strands circulate aside from one end as though we unzip a zip.

In layman's terms, they split apart into 2 ladders from one end to the other and then zip back together as two identical ladders.
Enzymes (protein molecules) are the ones in charge of this splitting process. They have an electrical charge that tells the molecules to disassemble from one end to the other.
Next, the enzymes re-assemble the split ladders by grabbing the protein and sugar molecules needed to reconstruct two more identical ladders from one end to the other.
It's like a zipper.

It can uncoil(unzip) during DNA replication, by DNA polymerase
