Question
Chapter 27.3, Problem 27.3CIAP
Interpretation Introduction
Interpretation:
Why Taq polymerase used in PCR instead of the DNA polymerase found in humans has to be explained.
Concept Introduction:
Polymerase chain reaction (PCR):
Polymerase chain reaction (PCR) is a technique which is used for amplification of DNA strand by thermos aquaticus polymerase (Taq polymerase).
Taq polymerase is an enzyme which is used in the PCR reaction because it can withstand very high temperatures because PCR reaction involves different temperatures; denaturation temperature (

Why is it necessary to use a special DNA polymerase(Taq polymerase) in PCR?
Most PCR reactions do not use the more expensive types of DNA polymerase, which have DNA proofreading. How might this be a problem in accurately copying specific DNA sequences of the target gene?
Both cloning and PCR can be used for making copies of DNA. What is the advantage or limitation of one over the other?

- Put the steps of one PCR cycle in the correct order: The PCR reaction mixture is heated to about 70 degrees, which is the optimum temperature for the polymerase to build the new strands of DNA, starting at the 3' end of the primer. The PCR reaction mixture is heated to 95 degrees Celsius, which denatures the double stranded template DNA. The PCR reaction mixture is cooled to about 50-55 degrees, which allows the primers to find their complementary site on the template and "anneal" thearrow_forwardWhy Touch-down PCR technique is better than the Gradient PCR technique?
