What holds the bases together in DNA?
hydrogen bonds
The bases in DNA (Adenine, Thymine, Guanine, and Cytosine) are held together by hydrogen bonds. Specifically, Adenine forms two hydrogen bonds with Thymine, while Guanine forms three hydrogen bonds with Cytosine. These hydrogen bonds are strong enough to hold the two strands of the DNA double helix together, while still allowing for easy separation during DNA replication and transcription.
