What are the three advantages of PCR?

PCR is a method of cloning alleles, making millions of replicas from trace quantizes or fragment DNA.

1. PCR can amplify STR in any amount needed to successful profiled, so very small samples or degraded samples are less of a problem.

2. STR profiling can be completed in a fraction of the time required for the VNTR.

3. It is not necessary to work with any radioactive labeled probes or X-ray film.
