WebFirst, a PCR can’t be any better than the primers. If your primers don’t pick up the target due to a mutation, that sequence will drop out. In the primer region, you can’t trust the sequence at all. Second, PCR can mangle your sequence, particularly around repeats. WebAlongwith advantages, PCR is also associated with limitations, beyond which the technique does not hold good. Due to its high sensitivity, a small contamination on its sample culture (be it even trace amount of DNA), reading errors are produced.
