In addition, when proteins are being made, the double helix unwinds to allow a single strand of DNA to serve as a template. This template strand is then transcribed into mRNA, which is a molecule that conveys vital instructions to the cell's protein-making machinery.
The DNA helix consists of two complementary DNA strands. Therefore, each of the two strands serves as a template for the construction of the other strand. Under normal conditions the DNA is packed into a compact structure called chromatin. To be able to replicate, the cell has to unfold and unwind the DNA, and also has to separate the two strands from each other. The cell has a complex machinery to perform these tasks.
