Answer:
Sequence a DNA fragment.
Explanation:
Dideoxyribonucleotides may be defined as the DNA molecule that lacks hydroxyl group at 2 and 3 position of the pentose sugar. These molecule are important in the molecular biology.
The sequencing of a DNA fragment means to determine the sequence of the nucleotides in a DNA molecule. The dideoxyribonucleotides is used to tag the target DNA fragment and known the sequence of the target DNA molecule.
Thus, the correct answer is option (C).
