You are presented with the question "What do the building blocks of DNA bind together to form?" and the following answer choices: 
- A compound that donates proton
 - colors of the spectrum
 - Electrical energy
 - chain called a polynucleotide
 - Something with exactly eight protons
 - Something that makes plants green
 - Something with a head, thorax, and abdomen
 - biological diversity

Now knowing that many nucleotides bind together to form a chain called a polynucleotide and nucleotides are the building blocks of DNA , choose the best answer.
