Answer:
DNA polymerase
Explanation:
DNA polymerase is the enzyme that synthesizes a new radiolabeled or non-radiolabeled DNA strand. It has the ability to add nucleotides at the 3'OH end of a paired region of DNA, causing the chain to extend in the 5 '→ 3' direction.
Eukaryotic cells have several types of DNA polymerases such as α, δ, β, ε, and, where α, δ, β and ε are located in the nucleus, and are located in mitochondria.
