When mitosis occurs, the DNA inside the cell's nucleus must replicate. The new cell that is formed has an identical copy of its

parent cell's DNA. That means it has the same information coded in its genes. During DNA replication, how is an accurate new copy of DNA formed?
DNA polymerases add nucleotides to the exposed base pairs according to base-pairing rules.

During DNA replication uracil bases hold the place of all thymine bases until the newly formed double helix is able to form hydrogen bonds.

DNA helicases add nucleotides to the exposed bases and ensure the formation of hydrogen bonds

The answer is <span>DNA polymerases add nucleotides to the exposed base pairs according to base-pairing rules.

DNA polymerase performs the polymerization of DNA. It adds nucleotides to the new DNA strand according to the base-pairing rules. This means that adenine binds to thymine and guanine binds to cytosine. The DNA polymerase is important enzyme responsible for accurate DNA  replication.

Choice 2 is incorrect because DNA does not contain uracil.
Choice 3 is incorrect because helicase untwists DNA.</span>
