DNA double helix is stabilized by:

RankGuru · Accepted Answer

According to the **Watson-Crick Model** of DNA:
- The two strands are held together by **Hydrogen Bonds** between complementary nitrogenous bases.
- **Adenine (A)** pairs with **Thymine (T)** via 2 H-bonds.
- **Guanine (G)** pairs with **Cytosine (C)** via 3 H-bonds.
- Hydrophobic interactions and van der Waals forces between base stacks also contribute to the stability of the double helix.
