Question

which enzyme is responsible for adding complementary nucleotides during dna replication? dna polymerase helicase ligase rna polymerase topoisomerase

Explanation:

DNA polymerase is the enzyme that synthesizes new DNA strands by adding complementary deoxyribonucleotides to the growing chain during DNA replication. Helicase unwinds the DNA double helix, ligase joins DNA fragments, RNA polymerase synthesizes RNA, and topoisomerase relieves DNA supercoiling.

Answer:

A. DNA polymerase
