1. The double helix structure of DNA is stabilized by hydrogen bonds between complementary base pairs (A-T and G-C) and hydrophobic interactions between stacked bases.
2. The sugar-phosphate backbone forms the outer framework, with phosphate groups linked by phosphodiester bonds to deoxyribose sugars.
3. The antiparallel orientation means one strand runs 5' to 3' while the complementary strand runs 3' to 5', allowing proper base pairing and structural stability.
4. Base stacking contributes significantly to helix stability through van der Waals forces and hydrophobic effects in the core of the helix.
5. The major and minor grooves provide binding sites for proteins that regulate gene expression and DNA replication.
