The correct answer is be sure that your instrument is calibrated properly. If your instrument isn't calibrated, then your data will be inconsistent.
If the DNA polymerase did nothing special when a mispairing occurred between an incoming deoxyribonucleoside triphosphate and the DNA template, the wrong nucleotide would often be incorporated into the new DNA chain, producing frequent mutations. The high fidelity of DNA replication, however, depends not only on complementary base-pairing but also on several “proofreading” mechanisms that act sequentially to correct any initial mispairing that might have occurred.
That can be true. Everyone (mother) is different. That usually goes away after nursing for awhile.
