Answer:
<em>The correct option is D) The four nitrogen bases of DNA combine is threes to produce only 20 amino acids.</em>
Explanation:

The genetic code which codes for a certain amino acid remains the same for all types of organisms whether be prokaryotes, animals or plants. Hence, the genetic code is considered universal as the four nitrogen bases combine to form only the 20 different amino acids in all types of organisms alive.
