For which of the following processes can dideoxyribonucleotides be used?

a) separate dna fragments
b) produce cdna from mrna
c) sequence a dna fragment
d) visualize dna expression

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).

answer; i believe the correct answer is (replication is not conservative);

answer; /// i believe that the correct answer is ( monophasic ); ethinyl estradiol- ethynodiol diacetate is a monophasic oral contraceptive agent; ///
