Using computer simulations, a team of University of Wisconsin-Madison researchers has identified some of the pathways through which single complementary strands of DNA interact and combine to form the double helix.
Present in the cells of all living organisms, DNA is composed of two intertwined strands and contains the genetic "blueprint" through which all living organisms develop and function. Individual strands consist of nucleotides, which include a base, a sugar and a phosphate moiety.
