One drawback to polymerase chain reaction (PCR)is:
A) The process is easily contaminated.
B) The process takes a very long time to make the replications of DNA.
C) The results of the PCR test are very technique dependent, so that different technicians can get different results.
D) Patient care may be compromised if false-positive PCR results are generated.

Because PCR is so sensitive,small amounts of extracted nucleic acid or carryover amplicons from previous PCR assays can contaminate future PCR assays.This may result in false-positive results.When contamination occurs,all equipment and work surfaces must be thoroughly cleaned,and new reagents (including primers)usually must be used.Laboratories that perform PCR and other amplification methods should,if possible,use separate rooms for template extraction,PCR reagent preparation,and amplification.
