The double helix structure is the three-dimensional shape of DNA, consisting of two intertwined strands that form a spiral, held together by complementary base pairing. This configuration is crucial for the replication and storage of genetic information, enabling the transmission of hereditary traits from one generation to the next.

Base pairing is a fundamental principle of molecular biology where specific nitrogenous bases in nucleic acids form hydrogen bonds with their complementary bases, ensuring the accurate replication and transcription of genetic information. In DNA, adenine pairs with thymine and cytosine pairs with guanine, while in RNA, adenine pairs with uracil instead of thymine.
