A researcher has a very small sample of DNA and needs to make millions of copies in order to study a specific gene. Because the original amount of DNA is insufficient for experiments like sequencing or cloning, the researcher decides to use a laboratory technique that can rapidly amplify the DNA. Question:Which technique should the researcher use to amplify the DNA, and what is the basic principle behind it?

A researcher is using genomics approaches to identify pathogens in patient samples by analyzing their DNA. While this method works well for most microbes, the researcher notices that certain infectious agents cannot be reliably detected using standard genomics techniques. Question:Which type of pathogen would genomics NOT be effective in detecting?

A patient is diagnosed with a bacterial infection, and the doctor prescribes a class of antibiotics that work by disrupting the enzymes responsible for maintaining DNA structure during replication. By targeting these enzymes, the drugs prevent the bacteria from properly replicating their DNA, stopping their growth. Question:Which enzymes are specifically targeted by quinolone antibiotics in bacteria?
