The bases in DNA are held together by hydrogen bonds.
Step-by-step explanation:
The bases in DNA are held together by hydrogen bonds. DNA is made up of four different bases: adenine (A), thymine (T), cytosine (C), and guanine (G). These bases form pairs, with adenine always pairing with thymine and cytosine always pairing with guanine.
