Which of the Following Best Explains the Enzyme(s)involved in Ribonucleotide

Question

Which of the following best explains the enzyme(s)involved in ribonucleotide reduction?
A)there is 1 enzyme for each of the 4 different nucleotides
B)1 enzyme for pyrimidine nucleotides and 1 for purine nucleotides
C)1 enzyme for pyrimidine nucleotides,1 for ADP and 1 for GDP
D)1 enzyme for purine nucleotides,1 for CDP and 1 for UDP
E)1 enzyme for all 4 nucleotides

Accepted Answer

Ribonucleotide reductase is the enzyme responsible for converting ribonucleotides into deoxyribonucleotides, and it acts on all four nucleotides using the same enzyme.
