Quizplus · Accepted Answer

The three types of units that must be present in a deoxyribonucleotide used in forming DNA are:
I. Base

IV. Phosphate
Therefore, the best choice is B as it includes I, II, and IV. Choice A includes water, which is not a component of a deoxyribonucleotide. Choice C includes ribose instead of deoxyribose, which is not present in DNA. Choice D includes all the correct components, but also includes water which is not a component of a deoxyribonucleotide.
