Answer 1

DNA amplification with a higher error rate using PCR and Taq polymerase is called PCR-based mutagenesis, used for studying gene function and creating modified organisms.

Step-by-step explanation:

When a scientist amplifies a region of DNA using PCR conditions which increase the error rate of Taq polymerase, they are performing a process known as PCR-based mutagenesis. This intentional introduction of mutations is often used for studying gene function, protein interactions, or for creating genetically modified organisms with new traits. The use of Taq polymerase, which is a DNA polymerase isolated from the thermostable bacterium Thermus aquaticus, is crucial for the high-temperature steps of PCR. By increasing the error rate during PCR, scientists can introduce mutations in the DNA sequence, which can then be analyzed for various research purposes.
