PCR can be used to amplify DNA approximately a billion times in just about 35-40 cycles.

DNA collection and analysis is an integral part of CSI, and the samples obtained are often extremely low in concentration and low quality.

Thus, PCR is routinely used to amplify this DNA to amounts that can be analyzed further by methods such as fingerprinting, sequencing, etc. to identify people involved in the crime.
