Question

How does the polymerase chain reaction make DNA fingerprinting more reliable?

Answer 1

Answer:

C. It allows scientists to quickly make many copies of DNA.

Explanation:

• Polymerase chain reaction (PCR) is a technique using which several copies of a DNA template can be made.
• For DNA fingerprinting the DNA is usually obtained from samples such as hair, saliva, blood, etc.
• The amount of DNA in samples such as hair or saliva is not enough and thus, amplification of the amount using PCR allows a much reliable DNA fingerprinting to take place.

Answer 2

The polymerase chain reaction makes DNA fingerprinting more reliable because it allows scientists to quickly make many copies of DNA the answer is C
