It returns to its original shape, and is reused. Look up the 'lock and key' and 'induced fit' models.
The first step in DNA synthesis is the unwinding of the double-stranded DNA molecule by an enzyme called helicase. This process separates the two strands of DNA, creating a replication fork where the synthesis of new DNA strands can occur.

The enzyme that separates the two strands of the DNA helix during replication is called helicase. It unwinds the double helix by breaking the hydrogen bonds between the base pairs, allowing each strand to serve as a template for the synthesis of a new complementary strand.
An enzyme-substrate complex is formed when a subtrate molecule binds with the active site of an enzyme that is of similar shape and size. The active site of the enzyme will alter slightly to combine with the substrate molecule. This will put an strain on a particular bond of the substrate molecule, which will lower the activation energy for the reaction as the bond will break more readily. The substrate is then catalysed.
"... errors are corrected in DNA is through the use of the enzyme DNA polymerase. This enzyme is the same one that matches nucleotides that create a new strand to the old strand of a molecule of DNA. After DNA polymerase creates the new molecule of DNA, it checks its work, to make sure that it didn't try to match a nucleotide with its incorrect pair." -taken from last editors paper.

Enzymes unwind DNA!
RNA polymerase is the enzyme that connect the new nucleotides together and proofreads them.

the DNA polymerase III
First, the DNA double helix unwinds and separates into two strands. Then, each strand serves as a template for the synthesis of a new complementary strand. This process is carried out by enzymes that help assemble the new DNA strands.
DNA splits, and mRNA and tRNA are there to create new strands for the new replicated DNA strand. This is what happens prior to mitosis in cell division.
DNA ligase is the enzyme responsible for creating the covalent bonds that connect the sugar-phosphate backbone of the new DNA molecule during DNA replication and repair processes. It seals the nicks between adjacent nucleotides to form a continuous DNA strand.
