How does the structure of DNA relate to its function?

The structure of DNA, with its double helix shape and complementary base pairing, is crucial to its function as the genetic code of living organisms. The sequence of nucleotides along the DNA strand contains the instructions for producing proteins, which are essential for the functioning and development of cells. Additionally, the specific arrangement of the bases allows for accurate replication during cell division, ensuring the inheritance of genetic traits. Understanding the structure of DNA is fundamental to comprehending its role in inheritance, genetic variation, and the basis of life itself.
