The mRNA strand!
DNA replication is a process where the double-stranded DNA molecule is unwound, or unzipped, by enzymes called helicases. This unwinding allows for the separation of the two parental DNA strands, which then serve as templates for the synthesis of new DNA strands.
Templates.
The Double Helix
Various enzymes, such as topoisomerases and helicases, actively prevent the unwound DNA from twisting back by releasing the supercoiling tension and unwinding the DNA strands, respectively. Additionally, DNA-binding proteins help stabilize the unwound DNA structure to maintain the separation of the two strands.

One strand of RNA is transcribed from each of the two unzipped strands of DNA during transcription. RNA polymerase synthesizes a complementary RNA strand to one of the DNA strands.
The location where the DNA molecule becomes unzipped is called the replication fork. This is where the two strands of the double helix separate during DNA replication to allow for the synthesis of new complementary strands.
Unwound DNA is called single-stranded DNA (ssDNA). This type of DNA consists of a single strand of nucleotides, as opposed to the double helix structure formed by two complementary strands of DNA. Single-stranded DNA is often involved in processes such as DNA replication and gene expression.
DNA polymerase attaches (polymerizes) nucleotides together to make polynucleotides using a strand of DNA that has already been unzipped by DNA helicase.
A strand of DNA can be "unzipped" on its own or by human intervention to replicate. This process does not harm the DNA and provides a carbon copy of itself.
