Describe how the polymerase chain reaction (PCR) works. What are the three steps in a PCR cycle and what is happening at each step?
Homework Answers
Answer:
The polymerase chain reaction is a process of DNA amplification which produces large copies of DNA molecules from the template strand.
There are 3 important steps of PCR
-
Denaturation: double-stranded DNA is separated into single-stranded DNA at high temperature (94C), this separation is necessary for primer binding
-
Annealing: Annealing of primers (short DNA fragments) complementary to 3’ end of the DNA at 54C.
-
Extension: Active DNA polymerase initiates polymerization synthesizing DNA over the template strand (72C).

Polymerase chain reaction (PCR): The gold standard of nucleic acid amplification The polymerase chain reaction (PCR) is a powerful tool for amplifying genetic material (that is, making many copies of it). This technique can be used for a wide range of applications, from examining and manipulating the specific genes involved in making L. monocytogenes pathogenic to analyzing the phylogenetic relationships between microbes.

Polymerase Chain Reaction (PCR) uses a special heat-stable DNA polymerase (Taq polymerase) that is slightly less accurate than DNA polymerase (Pol I) purified from E. coli. Taq polymerase will therefore introduce wrong bases into a growing DNA chain more frequently than will Pol I. In which one or more of the following applications of PCR will this type of inaccuracy be a problem? Explain why. Detection of bacterial DNA in infected tissues from patients. Detection of viral RNA in infected...

Primers are short pieces of DNA that are used in PCR (Polymerase Chain Reaction), the process which is used in molecular labs to make copies of short stretches of a gene or genome. You have designed primes that have a Molecular Weight (MW) of 6000. It arrives as a dry sample in the quantity of 300 µg. How much water do you need to add to make a primer stock solution of 100 mM primers? HINTS: Remember that mM is...

1.The PCR (polymerase chain reaction) protocol that is currently
used in laboratories was facilitated by the discovery of a
bacterium called Thermus aquaticus in a hot spring inside
Yellowstone National Park, in Wyoming. This organism contains a
heat-stable form of DNA polymerase known as Taq
polymerase, which continues to function even after it has been
heated to 95°C.
a.Why would such a heat-stable polymerase be beneficial in
PCR?
b.What would happen if it weren’t
heat stable?
c.How might you choose...
