Describe how the polymerase chain reaction (PCR) works. What are the three steps in a PCR cycle and what is happening at each step?
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. What are the steps of PCR required to amplify the recombinant DNA? Drag and drop the events into...
Explain the polymerase chain reaction and include all starting materials required, what happens in each cycle, and how a scientific investigation might benefit from PCR.
Describe three steps of a cycle of PCR.

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...
Question 33 (2 points) The requirements of the polymerase chain reaction (PCR) include: a) knowing parts of a target DNA sequence to be amplified. b) two primers, complementary to each end of the target sequence. c) a large supply of DNA nucleotides. d) a heat-stable DNA polymerase. e) All of the above
polymerase chain reaction, many copies of regions of the genome for a number of different downstream applications. In this Project you are PCR-amplifying your mitochondrial HVR1 region so that you can obtain the DNA sequence for that region. The ultimate goal is to determine your haplotype or haplogroup based on that region, which will provide you with insight into your deep ancestry. consider the class discussions you had on PcR this week. Use this information to answer the following questions:...
