Final answer:
DNA serves functions in inheritance and protein synthesis. Its structure, a double helix, determines its function through the arrangement of nucleotides.
Step-by-step explanation:
DNA serves two essential functions: inheritance and protein synthesis. DNA is responsible for passing genetic information from parent to offspring, and it is replicated with high accuracy to maintain the integrity of this information. DNA also directs the construction of proteins necessary for cell growth and reproduction.
The structure of DNA influences its function through the arrangement of nucleotides. DNA is composed of two strands that form a double helix. The sequence of nucleotides along the strands encodes the genetic information. The specific base pairing between nucleotides ensures accurate replication and protein synthesis.
