What is the main advantage of using PCR in DNA fingerprinting?

What is the main advantage of using PCR in DNA fingerprinting?
  1. It allows for the detection of VNTRs with greater sensitivity.
  2. It enables the isolation of DNA from a wider variety of sources.
  3. It reduces the number of steps required for DNA fingerprinting.
  4. It eliminates the need for the use of a VNTR probe.

Solution

The paragraph mentions that the sensitivity of the technique has been increased by the use of PCR, which allows DNA fingerprinting to be performed with DNA from a single cell.
