What provides the energy for the polymerization reactions in DNA synthesis?

Question

Quizplus · Accepted Answer

The deoxyribonucleotide triphosphate substrates provide the necessary energy for polymerization reactions in DNA synthesis. As each nucleotide is added to the growing DNA strand, two phosphates are cleaved off, releasing energy that drives the reaction forward. ATP provides energy in other cellular processes but is not directly involved in DNA polymerization. DNA polymerase is the enzyme that facilitates the polymerization reaction but does not provide energy, and breaking the hydrogen bonds between complementary DNA strands requires energy rather than providing it.
