Forensic DNA fingerprinting often involves recovery of minute quantities of DNA from a crime scene.What is a concern in analyzing this DNA?
A)There is seldom enough DNA to allow PCR amplification.
B)Even with these tiny amounts of DNA,there may be too much DNA for efficient PCR.
C)Restriction enzymes may not work efficiently on the PCR-amplified DNA.
D)It is critical to avoid the introduction of contaminating human DNA unrelated to the crime.

Question

Quizplus · Accepted Answer

It is critical to avoid contamination of the DNA sample with unrelated human DNA, as this could lead to false results and incorrect conclusions. Careful sample collection and handling, as well as using proper laboratory procedures, can minimize the risk of contamination. The other options (A, B, and C) are not generally concerns in analyzing DNA from a crime scene, as there are sophisticated techniques available to amplify and analyze even very small amounts of DNA.
