Which of the following statements regarding the fidelity of DNA replication is true? OI. DNA polymerase has a 3'-5' exonuclease activity that removes incorrectly paired nucleotides. O The DNA polymerase active site is highly flexible and can easily "fit" incorrectly paired incorporated nucleotides. DNA polymerase never makes an error in the nucleotide being incorporated. O II. -v The stability of base pairing is not a factor in controlling the fidelity of nucleotide incorporation during replication. y DNA polymerase has evolved to make errors at a relatively high rate because this is what drives evolution.

Viral Replication

The virus is acellular and considered non-living outside the host cell. The replication of the virus occurs only inside the living cells. Only a few genes are present in the smallest virus, whereas many genes are present in the largest virus. These genes encode specific viral proteins.
