Image of DNA (deoxyribonucleic acid) unwinding and creating two new daughter molecules. The DNA molecule is a double helix whose strands are linked by base pairs. DNA encodes genetic information in the sequence of these bases (adenine, guanine, cytosine, and thymine). The coiling strands are made from a sugar phosphate polymer. When DNA replicates the strands unwind and act as templates for the new molecules.
