The possibility of magnifying contaminating sequences present in a nucleic acid pool is a drawback associated with PCRs high level of sensitivity (i. e., potential for exponential amplification). A. True
B. False

True

Explanation:

The Polymerase Chain reaction (PCR) is a technique widely used in molecular biology to identify specific DNA fragments generally in a size range of 100 to 1000 base pairs (bp). PCR sensitivity refers to the potential of the PCR technique to specifically amplify the desired sequence in the sample. PCR is a highly sensitive (and also specific) method with values around 100% if the experimental conditions are proper. However, to reach these values, it is imperative to work in optimal conditions by eliminating contaminant factors in the sample which may alter PCR amplification.

answer; /// i do believe its (heredity); good luck
