In DNA, the correct base pairing follows specific complementary rules where certain nitrogenous bases bond with each other. Adenine always pairs with Thymine, forming two hydrogen bonds between them. This pairing is fundamental to maintaining the double-helix structure of DNA.

The structure of DNA is such that these base pairs fit into the helix, allowing for the genetic information to be stored and transmitted accurately during processes like replication. Adenine's pairing with Thymine is essential for the stability of the DNA molecule and ensures that when DNA replicates, the proper sequence of bases can be maintained.

Understanding this base pairing is crucial for molecular biology, genetics, and understanding how genetic information is expressed and inherited. The correct pairing is vital in processes such as transcription and translation, where the sequences of DNA are used to produce RNA and subsequently proteins.
