The polymerase chain reaction makes dna fingerprinting more reliable because it:

a. allows the use of a larger amount of dna for testing.

b. allows the use of rna instead of dna for testing.

c. allows bacteria to produce copies of dna.

d. allows the use of transgenic organisms in testing.

A. allows the use of a larger amount of DNA for testing.

Explanation:

Polymerase Chain Reaction(PCR) is a reaction is a widely used laboratory technique in biology specifically molecular biology.

It requires the use of DNA samples to carry our forensic research or DNA fingerprinting. It can also be used for viral screening of samples.

Polymerase Chain reaction replicates a small amount of quantity of DNA samples into a larger amount in order to carry out adequate tests or research on the samples.

The polymerase chain reaction makes DNA fingerprinting more reliable because it allows the use of a larger amount of DNA for testing.
