What structure is formed by two interlocking helixes in DNA?

The structure formed by two interlocking helixes in DNA is known as the double helix. This term describes the shape of DNA, which consists of two long strands that wrap around each other, resembling a twisted ladder. The double helix structure is crucial for DNA's function as it allows for the storage of genetic information in a stable form, while also providing mechanisms for replication and protein synthesis.

In the context of DNA, the strands are composed of nucleotides, and the pairing of the bases on these strands is essential for the accurate transmission of genetic information. The double helix structure was first described by James Watson and Francis Crick in 1953, which was a pivotal moment in molecular biology. This unique configuration not only protects the genetic material but also offers flexibility for the DNA to interact with proteins and undergo various processes such as replication and transcription.

Other structures mentioned, like the single helix, triple helix, and alpha helix, do not accurately describe the DNA configuration. The single helix would imply a simpler strand, while the triple helix suggests an additional layer that does not naturally occur in standard DNA. The alpha helix, on the other hand, refers to a common secondary structure in proteins, not in
