how do you compare a DNA molecule to a zipper

The pairing of the bases produces a long, two-stranded molecule that is often compare to a zipper. If you look at a zipper, the sides of the zipper represent the sugar and phosphate units, while the teeth of the zipper represent the pairs of nitrogenous bases of the DNA.

Comparing the different nitrogenous bases bond to each other in zipper pattern . you have the sugar , phosphate , and bases , and different bases line up on opposite side of the helix.
