PCR, shorthand for polymerase chain reaction, is a nice example of how much of biotechnology works. Through fundamental biological studies, an enzyme or other molecule is discovered with useful properties that can be repurposed for other applications. PCR is an example of how DNA polymerase can be used to make a large number of double-stranded DNA copies of a locus of choice in a test tube. A. Ignore for now how this is possible, but assume you were able to order a tube filled with DNA polymerase protein from a biotechnology company. One enzyme you ordered is called Taq, an enzyme from Thermus aquaticus (a bacteria isolated from hot springs in Yellowstone) that is homologous to DNA Polymerase I in E. coli. This might seem strange at first, as you should know that DNA Polymerase III carries out the majority of DNA replication inside bacterial cells. What are some features of DNA Polymerase I that would make it more robust and easy to isolate than DNA Polymerase III?

Explanation / Answer

Yes ofcourse, your thinking is in a right way as DNA ploymerase I i more abundant than DNA polymerasE III. and DNA polymerase III is farthest from the orign of replication. They way of approach for this answer from your side is good and its in a correct way.
