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.
Answer:
The correct option is B, THE LOCATION OF THE FOSSILS WERE ONCE MUCH CLOSER TO EACH OTHER.
Explanation:
The discovery of identical species of organisms at different location on the earth continent has been explained by the theory of plate tectonic. The theory of plate tectonic states that the outer layer of the earth is divide into several plates, which are capable of moving around the earth in relative positions to one another.
Using the theory of plate tectonic, the geologists in this question will conclude that the fossils discovered at different sides of the ocean were closer together before, but were moved away from each other as a result of the process of plate tectonic.
Whats your question..........
Answer:A mutation is a change in a DNA sequence. Mutations can result from DNA copying mistakes made during cell division, exposure to ionizing radiation, exposure to chemicals called mutagens, or infection by viruses.
Explanation:
DNA replication occurs within the nucleus of a cell
