What type of bonds hold a DNA double helix together?
The two chains of a double helix are held together by hydrogen bonds between specific bases in each chain. A guanine base (G) is linked to cytosine (C) in the opposite chain with hydrogen bonds. Similarly, an adenine base (A) is linked to thymine base (T) in the opposite chain.
