What is the structure of DNA described as?

The structure of DNA is accurately described as a double helix. This term refers to the two intertwined strands that make up the DNA molecule, resembling a twisted ladder. Each strand consists of a backbone made of sugar and phosphate groups, while the rungs of the ladder are formed by pairs of nitrogenous bases (adenine with thymine, and cytosine with guanine) that are bonded together through hydrogen bonds.

This double helix configuration is crucial for DNA's function in storing genetic information and allows for the accurate replication of DNA during cell division. The stability provided by the double helix structure helps protect the genetic code from damage and provides a mechanism for the two strands to separate during replication and transcription, facilitating the processes necessary for cellular function and reproduction.
