How has this technology impacted medicine, forensics, or agriculture?
Instead of the process taking years, scientists are able to clone, sequence, and identify a new gene in about a week. In medicine, PCR is used to screen for hereditary diseases. People at risk of a certain disease to predict the likelihood that their children will inherit the disease. PCR also can speed up research on emerging infectious diseases. PCR has also changed forensic science. Since PCR can amplify small amounts of DNA, paternity testing can now be performed on a single swab taken from someone's mouth
What are the potential problems associated with this technology?
Polymerase is widely used in multiple work forces and often reveals very important data. Unfortunately, a faulty enzyme or reagent can throw off the entire data, messing up any results.
What are the ethical considerations relevant to this technology?
Some people consider PCR unethical, because since DNA is produced so quickly and easily, it might be possible for outside sources to obtain a copy of it for their own use without the owner's permission. On the other hand, some people think that genetic engineering is unethical altogether, and believe that DNA should be left alone to replicate naturally
