taq polymerase is special because it is very stable at high temperatures and will not denature even at the 90 degree step of pcr. taq polymerase is so heat stable because it was extracted from the bacterium thermus aquaticus, which is found in hot springs and geezers

Could you use human polymerase for the extension step in the PCR reaction?
Actually the problem with the Human polymerase is the sensitivity to temperature if we talk about PCR. That is the reason why we use Taq DNA polymerase which is thermostable where as use of human polymerase may result in loss of its function due to high temperature.
Compare the polymerase chain reaction and DNA replication?
PCR need thermostable enzyme like taq DNA polymearse, while in replication using highly proofreading enzyme DNA polymerase. taq enzyme work in very high temprature while in replication our body temprature
What process involves using primer and Taq in detemining whether a person has a certain mutant gene?
The process used is PCR = Polymerase Chain Reaction. PCR used Taq polymerase - an enzyme that adds nucleotides to a primer and brings about the formation of new double stranded DNA. Primers are short sequences of nucleotides that bind to the mutant gene and allow the Taq polymerase to function. The ultimate result of the process is the amplification (creation of several million copies) of the mutant gene. In the absence of the mutate gene, these copies would not be created since the primers do not have anywhere to bind to.
PCR stands for?
PCR stands for Polymerase Chain Reaction.
What is main function of DNA polymerase?
The DNA polymerase enzyme synthesises the complementary DNA strand to a single stranded DNA strand (in vivo and in vitro). This often requires the presence of a 3' end for the polymerase enzyme to bind to before synthesis can begin. Taq polymerase (A DNA polymerase) is often used in PCR reactions to synthesise DNA in vitro using primers to provide a 3' end to bind to.
Why taq polymerase is thermostable?
Taq Polymerase is an important enzyme component involved in the PCR reaction. Its A DNA polymerase and its role is to elongate the growing strands of DNA during the extension process. Since the Extension process in a PCR works at a temperature which a human DNA polymerase cannot remain active, the Taq polymerase obtained from Thermus aquaticus (living in the hot springs) are used and hence these enzymes are thermo stable.
Why is a thermostable polymerase used in PCR?
The thermostable polymerase (or Taq polymerase) is a thermostable DNA polymerase (named after the thermophilic bacterium Thermus aquaticus from which it was originally isolated by Thomas D. Brock in 1965), is often abbreviated to "Taq Pol" (or simply "Taq"), and is frequently used in polymerase chain reaction (PCR). Taq polymerase is as an enzyme able to withstand the protein-denaturing conditions (high temperature) required during PCR; Therefore it replaced the DNA polymerase from E. coli originally used in PCR. Taq's optimum temperature for activity is 75-80°C, with a half-life of greater than 2 hours at 92.5°C, 40 minutes at 95°C and 9 minutes at 97.5°C, and can replicate a 1000 base pair strand of DNA in less than 10 seconds at 72°C.
What is the purpose of mgcl in pcr?
The enzyme DNA polymerase ( Taq polymerase) used in the PCR requires Mg 2+ ions for its functioning.These Ions act as cofactors for the enzyme . Hence the requirement for the use of Mg Cl2 in PCR reactions.
What is the enzyme that synthesized DNA used in PCR that distinguishes it from the equivalent enzyme that carry out the same function in our cells or those of most bacteria?
PCR uses Taq polymerase (a type of DNA polymerase that comes from the thermophilic bacterium, Thermus aquaticus).The difference between that version of the enzyme and the one that our cells use is that Taq polymerase functions at much higher temperatures, allowing it to withstand PCR temperatures for thermal cycling.
If e. coli DNA polymerase was used instead of thermus aquaticus DNA polymerase in a pcr polymerase chain reaction procedure what would happen?
Unlike Taq DNA polymerase, E.coli DNA polymerase is not heat-stable and will denature during the strand denaturation step of the PCR reaction.

What is PCR?
Taq are important in PCR because they are heat resistant and are required for polymerase action. Hence we use Taq Polymerase enzyme in PCR. Specially and their main role is "Heat Sensitive Polymerase Enzyme".
How did Taq DNA polymerase acquire its name?
The Taq name is a shortened for Thermophilus aquaticus, a thermophilic bacteria that is the source of the particular DNA polymerase enzyme. The enzyme heat resistant property is desired because it could withstand the high temperature during the PCR process. -Kaitlin The Taq name is a shortened for Thermophilus aquaticus, a thermophilic bacteria that is the source of the particular DNA polymerase enzyme.

Role of magnesium chloride in PCR?
mgcl2 acts as a cofactor for the DNA polymerase used and is necessary for efficient functioning of the pcr
Why PCR need gelatin?
According to Roche website, different additives allow optimization to increase yield and specificity of PCR reactions. DMSO, for instance, is reported to reduce nonspecific priming, while gelatin and glycerol stabilize Taq DNA polymerase during PCR, which generally increases the yield.
