Like a zipper a DNA molecule has two "spines" and jutting out "teeth" that lock together to join the spines.
When DNA replicates, it "unzips".
The initial step in the replication of DNA is the lengthwise separation of the helical strand into two separate parts. It's not a leap to see DNA separating down the middle much as a zipper opens down the middle when it is unzipped.

During the processes of DNA replication and transcription, the two strands of the DNA molecule separate, or "unzip", so that the two strands can be copied by DNA nucleotides, or the anti-sense strand of DNA can be transcribed by mRNA.
DNA replication is a process during which DNA double helix opens like a zipper , new nucleotides are added along both strands of DNA by enzyme DNA polmerase and at last two molecules of DNA are formed. It takes place in S phase of interphase .
DNA Molecules
DNA helicases are proteins, while DNA molecules are nucleotides.
Daughter moloqules are newer than DNA moloqules
because the shape is a double helix. so it looks like a zipper and connects to each other.

DNA replication begins in areas of DNA molecules are called origins of replication.
The sides of the DNA ladder are alternating deoxyribose (sugar) molecules and phosphate molecules. The DNA bases attach to the sugar molecules.
