The invention of PCR make DNA fingerprinting possible because "PCR made it possible to produce enough copies for reliable tests".

Option: C

Explanation:

With the development of the PCR technique, DNA profiling has made enormous progress both in its distinguishing capacity and in its ability to survive information from very limited or damaged beginning samples. The PCR cycle mimics the biochemical mechanism of DNA replication yet restricts it to fragments of concern unique to DNA.

In the PCR method, the specimen of DNA is denatured by heating into separate polynucleotide strands. Two primers of DNA oligonucleotides are used for hybridization on opposite DNA strands to two matching nearby sites. Thus two new copies of the interest sequences are produced. Quantitative PCR methods allow accurate, high and automated calculations of the throughput.

the principles and empirical processes of discovery and demonstration considered characteristic of or necessary for scientific investigation, generally involving the observation of phenomena, the formulation of a hypothesis concerning the phenomena, experimentation to test the hypothesis, and development of a conclusion that confirms, rejects, or modifies the hypothesis.

you know that this symptom is misleading and quite often is related to: heart attack

a heart attack is a condition that occurs when the blood flow that transports oxygen to the heart muscle is damaged or cut off completely. the coronary arteries that supply the heart muscle with blood flow can be blocked by the accumulation of plaque. also, when the plaque within the heart artery breaks, it creates blood clot that can also hinder the blood flow. men that are over 45years of age and women that are over 55years of age are at risk of having a heart attack. the symptoms of a heart attack include chest discomfort, chest pain, coughing, and shortness of breath.
