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.
One of four different nucleotide bases, which are ring-shaped molecules containing nitrogen, hangs off each sugar group. Two strands of DNA come together to form a twisted, ladder-like structure. Hydrogen bonds between the bases of each strand create the double-stranded structure. The cell must split the two strands to allow the replication machinery to access each strand and copy it. In eukaryotic cells, which have organized nuclei, DNA replication occurs in the resting phase, or interphase, of the cell cycle, in between rounds of cell division.
