</h2>
Explanation:
The DNA double helix (both strands of DNA) are held closs together by i) mainly hydrogen bonds between complementary bases and ii) the Van der Waals base-stacking interaction.
The hydrogen bonds between the base pairs form the double helical structure of DNA. There is no exchange or sharing of electrons in hydrogen bonds.
G always pairs with C with three hydrogen bonds and T always pairs with A with two hydrogen bonds.
