OVERVIEW In this activity, students build a paper model of DNA and use their model to explore key structural features of the DNA double helix  DNA and other protein - DNA complexes Proc Natl Acad Sci USA 1994 ; 91 : 6948-6952 13 Timsit Y DNA structure and polymerase fidelity J Mol Biol 1999

The DNA molecule is a long, coiled double helix that resembles a spiral staircase In it, two strands, composed of sugar and phosphate molecules, This means that each of the two strands in double-stranded DNA acts as a template to produce two new strands Replication relies on complementary base pairing,
