How many Hydrogen bonds are formed between Adenine and Thymine?

Adenine and thymine form two hydrogen bonds when they pair together in DNA. This is a key aspect of the base pairing rules, which establish how nucleotide pairs bond to create the structure of DNA. The specific arrangement allows for the stability and specificity of the double helix structure. The two hydrogen bonds that form between adenine and thymine create a relatively weak interaction compared to other types of bonding, but this is necessary for the DNA to be flexible enough to unwind during processes like replication and transcription. The two hydrogen bonds are crucial as they maintain fidelity in pairing while allowing for the easy separation of the two strands when required.
