What bond holds the bases together in a DNA molecule?

Answer 1

Base pairs in DNA are attached to each other via hydrogen bonds. The base pairs are attached to the backbone by covalent bonds.

Answer 2

Hydrogen bonds hold the bases together in a DNA molecule. These bonds form between specific pairs of nucleotide bases: adenine (A) pairs with thymine (T), and guanine (G) pairs with cytosine (C).

Answer 3

The bases of DNA molecules are held toghter by hydrogen bonds A bond with T by two h-bonds C bond with G by three h-bonds

Answer 4

A weak hydrogen bond. This allows the DNA strands to separate easily during transcription.

Answer 5

Between bases on the same chain of the double helix are covalent bonds.

Between paired bases on opposite chains of the double helix are hydrogen bonds.

Answer 6

hydrogen bonds

Answer 7

backbones
