Hydrogen Bonds
They are broken by the enzyme DNA helicase.
Nitrogen bases separate during the process of DNA replication and transcription when the hydrogen bonds between complementary base pairs (adenine-thymine and guanine-cytosine) are broken. This separation is facilitated by enzymes such as helicase, which unwinds the double helix structure of DNA, allowing the strands to be accessed for copying or RNA synthesis. The separation is crucial for the accurate duplication of genetic information or the production of messenger RNA.

Hydrogen bond
The nitrogen bases, adenine, uracil, guanine, thymine and cytosine are joined to each other via phosphodiester bonds. Hydrogen bonds hold the nitrogen bases in complementary DNA and RNA strands. Polypeptide bonds are formed between an amide and ketone, and these join amino acids in proteins. However, they do not hold nitrogen bases together.
