The invention of PCR make DNA fingerprinting possible because "PCR made it possible to produce enough copies for reliable tests".
<u>Option: C</u>
<u>Explanation:</u>
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.
All proteins are composed of amino acids. Each amino acid in a protein is linked by chemical bonds. Enzymes are composed of chains of amino acids. Enzymes are a type proteins that turn a cell into a highly developed miniature factory carrying out chemical reactions very fast.
