How do bases pair up in DNA replication?

In DNA replication, the nitrogen bases adenine and thymine, and guanine and cytosine form base pairs. The base-pairing rule states that in DNA adenine pairs with thymine and guanine pairs with cytosine, and in RNA adenine pairs with uracil. The paired nitrogen bases are held together with hydrogen bonds.


How do bases pair in DNA?

What are the rings of DNA made from?

If you mean the rungs of the twisted ladder model, they are made of the nitrogen bases of both strands held together by hydrogen bonds.


How are the DNA bases held together?

Hydrogen bonds


What type of bond holds nitrogen bases?

By nitrogen bases, do you mean the nitrogenous bases in DNA? If so, do you mean, what bonds are inside the bases, or what bonds hold pairs of these bases together in DNA? The bases themselves are constructed out of covalent bonds, but it is Hydrogen Bonding that holds pairs of these bases together. Hydrogen Bonds, despite their name, are not bonds like covalent bonds, but are a kind of intermolecular interaction that holds the nitrogenous bases of DNA together.
