Select the correct option:
Solution
Incorrect! Answer:
Hydrogen bonds between complementary bases
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.
