What type of bonds hold DNA base pairs together?

Explanation:
Hydrogen bonds hold DNA base pairs together. These non-covalent, relatively weak bonds form between complementary bases across the two strands, allowing the double helix to stay intact yet separate during replication and transcription. Adenine pairs with thymine through two hydrogen bonds, while cytosine pairs with guanine through three hydrogen bonds. The backbone is connected by covalent bonds along each strand, so the hydrogen bonds specifically link the bases between strands. Ionic or metallic bonds do not occur between the bases in DNA.
