Answer:
The answer is B.
Explanation:
Paracentric and Pericentric Inversions both are terms used to describe the action of inversing a part of the chromosome. But the main difference between the paracentric and pericentric inversions is that pericentric inversion, unlike the paracentric inversion, does include the centromere in the inversion process. So the answer is B, which is zero for paracentric inversion.

Answer:
(B) DNA polymerase recognizing a "mismatched" base pair, like adenine and guanine.
Explanation:
In DNA, adenine is always paired with thymine and guanine with cytosine. The DNA polymerase has 3' to 5' exonuclease activity which is also called proofreading activity. If a DNA polymerase adds the wrong nucleotide, it can not be translocated post the mismatched nucleotide. The pause allows the 3' to 5' exonuclease activity of DNA polymerase to remove the mismatched nucleotide followed by the addition of a correct nucleotide.
