- Scientists have reportedly isolated short fragments of DNA from fossilized dinosaur bones hundreds of millions of years old. The technique used to isolate this DNA is the polymerase chain reaction, which is capable of amplifying very small amounts of DNA a millionfold. Critics have claimed that the DNA isolated from dinosaur bones is not purely of ancient origin, but instead has been contaminated by DNA from present-day organisms such as bacteria, mold, or humans. What precautions, analyses, and control experiments could be carried out to ensure that DNA recovered from fossils is truly of ancient origin?arrow_forward(A) After three cycles of PCR, how many DNA molecules are present that correspond precisely to the desired amplification product?

- molecules continues to double every temperature cycle (referred to as a PCR cycle). (a) Suppose a sample containg x molecules is collected from a crime scene and is amplified by PCR. Express the number of DNA molecules as a function of the number n of PCR cycles. (b) There is a detection threshold of T molecules below which no DNA can be seen. Derive an equation for the number of PCR cycles it will take for the DNA sample Amplifying DNA Polymerase Chain Reaction (PCR) is a biochemical technique that allows scientists to take tiny samples of DNA and amplify them into large samples that can then be examined to determine the DNA sequence. (This is useful, for example, in forensic science.) The pro- cess works by mixing the sample with appropriate enzymes and then heating it until the DNA double helix separates into two individual strands. The enzymes then copy each strand, and once the sample is cooled the number of DNA molecules will have doubled. By repeatedly performing this heating…arrow_forwardWhy is DNA ligase so important in recombinant DNA technology? a.) It causes DNA to make multiple copies of itself. b.)
