Hydrogen bonds
Helicase
Base pairs in DNA are attached to each other via hydrogen bonds. The base pairs are attached to the backbone by covalent bonds.
cytosine and guanine form three hydrogen bonds between them
hydrogen bonds
Bases in DNA are linked through hydrogen bonds. There are two hydrogen bonds between Adenine and Thymine There are three hydrogen bonds between Guanine and Cytosine
Helicase
Hydrogen bonds
Hydrogen bonds are one of the weakest bonds, and aren't even true bonding of molecules, but rather a magnetic attraction between them. This particular bond is what allows the base pairs of DNA to properly link, as Adenine and thymine bond, and cytosine and guanine bond, but neither of these pairs bonds with elements from the other pair in this way.
Complementary bases in DNA are held together via hydrogen bonds. Between G and C there are three hydrogen bonds and between A and T there are two hydrogen bonds.

Thymine and adenine! Also guanine and uracil.
An acid is below 7 on the pH scale and bases are above 7 on the pH scale. An acid can be a hydrogen donor, and a base is a hydrogen acceptor.
