Before a zebra cell (or any eukaryotic cell) replicates its DNA, the first step is for the DNA to uncoil and unwind. This allows the two strands of the double helix to separate, exposing the nucleotide bases for replication.
Therefore, the correct response would be:
**The DNA unravels to make two strands.
The uppercase D N A unravels to make two strands.**
This refers to the unwinding of the DNA helix, preparing it for the replication process.
