Question

What is the relation of the structure of DNA to its function?

Answer 1

If you are talking about the general relation, then you are talking about the fact that the double helix and the trait of complementarity (A & T, G &C) allow for accurate and rapid replication of the DNA, which is necessary inheritance of the genetic material.

Answer 2

...can you be anymore vague?  there are A LOT of reasons

Answer 3

Structure of DNA is best suited for its function -

1. Inheretance - transfer of information from one generation to the other, it possible due to specific base pairing and semiconservative mode of replication. Daughter molecules are exact copies of each other.

2. Mutation - spontaneous mutations that are responsible for variation in species are possible due to tautomeric shift of electrons and altered pairing specificities leading o point mutations.

3. Storage of information - a blueprint for structure of proteins, genetic code of three nitrogen bases coding for one amino acid in universal and unambiguous manner is responsible for structure of proteins.

            What is expected of genetic material is possible only because of its structure.
