Answer:
(E) None of the above
Explanation:
All of the answers contribute to the high fidelity of DNA synthesis.
Accuracy of the DNA replication is achieved thanks to various mechanisms such as:
- DNA polymerase activity (high processivity)-ability of the enzyme to copy long stretches of DNA
- DNA polymerase proofreading-ability to recognize its own mistakes and fix them
- Cell's surveillance-cell monitors its DNA status, checks for the damage
- Mismatch Repair-cell contain repair machinery which recognizes DNA helix deformities, removes and replaces the portion containing the mismatch etc.
The new DNA molecule is identical to the original DNA.
Hope this helps! :)
