Question

The enzyme reassembles the newly copied dna molecules. the enzyme "reads" the original dna strand. A) DNA polymerase

B) Helicase
C) Ligase
D) Topoisomerase

Answer 1

DNA polymerase is the enzyme that reads the original DNA strand during DNA replication and synthesizes new complementary strands, ensuring the genetic information is accurately passed on to daughter cells(option a).

Step-by-step explanation:

The enzyme that “reads” the original DNA strand and reassembles the newly copied DNA molecules is DNA polymerase(option a).

This enzyme is essential for the process of DNA replication, where it synthesizes new strands of DNA by adding nucleotides that are complementary to the template strand. DNA polymerase requires a pre-existing strand or primer to add to; it cannot initiate synthesis on its own. This primer is provided by another enzyme called primase, which synthesizes a short RNA primer during DNA replication. Once the primer is in place, DNA polymerase extends the new DNA strand. This mechanism ensures that the genetic information encoded in the original DNA double helix is faithfully replicated and passed on to daughter cells.
