The difference between atp and the nucleoside triphosphates used during dna synthesis is that:
a. triphosphate monomers are active in the nucleoside triphosphates, but not in atp.
b. the nucleoside triphosphates have two phosphate groups; atp has three phosphate groups.
c. atp contains three high-energy bonds; the nucleoside triphosphates have two.
d. the nucleoside triphosphates have the sugar deoxyribose; atp has the sugar ribose.
e. atp is found only in human cells; the nucleoside triphosphates are found in all animal and plant cells.
