- In clear and concise terms, explain how the biochemical structure of DNA allows it to function as the genetic material. DO NOT write about chemical structure of the monomers. It is about the aspects of the structure of helix that enable it to function as the genetic material. Write your answer in your own words, in 5-6 lines,Examine the 5'- 3 sequence of bases of the DNA molecules (A D) shown below. I am only showing you the 5 - 3' strand of each molecule, but you can imagine the complementary 3' - 5' strand for each molecule. Which double-stranded molecule is held together by 10 hydrogen bonds?
