Severe destruction of DNA can be tested by:
Correct Answer: PCR
Description: PCR is an in vitro method for amplifying a selected DNA sequence that does not rely on the biologic (in vivo) cloning method.
PCR permits the synthesis of millions of copies of a specific nucleotide sequence in a few hours.
It can amplify the sequence, even when the targeted sequence makes up less than one part in a million of the total initial sample.
The method can be used to amplify DNA sequences from any source, including viral, bacterial, plant, or animal.
Key concept:
Polymerase chain reaction can even find cases with severe destruction of DNA.
