  • What is the substrate for DNA polymerase?
    The substrate for DNA polymerase is deoxyribonucleotide triphosphates (dNTPs).

    DNA helicase unzips the DNA.
  • How is base pairing involved in DNA replication?
    Base pairing ensures that complementary nucleotides are added to the new DNA strand, maintaining genetic accuracy.
  • Why does DNA need to replicate before cells divide?
    DNA must replicate before cell division to ensure each daughter cell receives a complete set of genetic information.
