Unraveling The Physics Of DNA's Double Helix

link:http://www.sciencedaily.com/releases/2007/07/070712134533.htm

Summary:Each DNA strand includes a sugar and phosphate "backbone" attached to one of four bases, which encode genetic sequences. The strength of the interactions within individual strands comes largely from the chemical attraction between the stacked bases. But the integrity of double-stranded DNA depends on both the stacking forces between base units along the length of the double helix and on the pairing forces between complementary bases, which form the rungs of the twisted ladder.

List three things you learned from this article in your own words.
1.The sugar and the phosphate are the backbone of DNA.
2.The strength of the interactions of the strands comes from the chemical attraction between the stacked bases.
3.The pairing forces between complementary bases and the stacking forces between base units form the rungs of the twisted ladder.
