Why cant DNA polymerase from organisms be used in pcr?
Many DNA polymerases from organisms are not suitable for PCR because they do not possess the optimal features required for the enzymatic reactions involved in PCR, such as high processivity, thermostability, and fidelity. PCR generally requires a DNA polymerase that can withstand the high temperatures used during the process without denaturing. Taq polymerase, isolated from the thermophilic bacterium Thermus aquaticus, is commonly used for PCR due to its ability to function at high temperatures.
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?
The enzyme used in PCR to synthesize DNA is called DNA polymerase. The key difference is that the DNA polymerase used in PCR, such as Taq polymerase, is derived from a thermophilic bacterium called Thermus aquaticus and can withstand the high temperatures used in the PCR cycling process. This distinguishes it from the equivalent enzyme in our cells or most bacteria, which would be denatured by the high temperatures of PCR.
PCR can be used to identify a bacterium because A.The DNA primers are specific B. DNA polymerase will replicate DNA. C. DNA can be electrophoresed. D. All cells have DNA. E. None of the above.?
A. The DNA primers in PCR are specific, meaning they will only bind to the target DNA sequence of the bacterium being identified. This allows for selective amplification of the target DNA, aiding in the identification process.
What is a PCR test used to identify?
A PCR test amplifies a single or few copies of DNA and creates potentially thousands or millions of copies. The most common reasons are for cloning, diagnosis of hereditary disease, genetic fingerprints, and analysis of genes.
What are some common questions about PCR that researchers often encounter?
Some common questions that researchers often encounter about PCR include: How does PCR work? What are the different types of PCR techniques? What are the limitations of PCR? How can PCR results be validated? How can PCR be optimized for better results? What are the potential sources of error in PCR? How can PCR be used in different research applications? What are the ethical considerations when using PCR in research? How can PCR be used in clinical diagnostics? What are the current advancements in PCR technology?

What organism is used primarily in PCR technique?
The organism used primarily in PCR (polymerase chain reaction) technique is a heat-stable DNA polymerase, such as Taq polymerase. Taq polymerase is derived from the thermophilic bacterium Thermus aquaticus, which can withstand the high temperatures required for PCR amplification.
Role of Taq polymerase in PCR?
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

Types of pcr and their significance?
there are; 1. RT PCR - helps in making complementary DNA with the help of mRNA. 2.anchored PCR - helps in making the DNA whose sequence is unknown.

What is pcr and types of pcr?
PCR is a biotechnological method to amplify your gene (DNA) of your interest. It produce millions of your DNA fragments hence used in cloning. There are variants of this method using the same thermocycling principle such as touch down PCR, gradient PCR, RFLP, multiplex PCR, Q PCR, RT PCR and so on.
What bacterium had the widest range of temperature tolerance?
Thermus aquaticus is a bacterium with a wide temperature tolerance, capable of surviving in temperatures ranging from 50°C to 80°C. It is known for its heat-resistant enzymes and is commonly used in molecular biology techniques like polymerase chain reaction (PCR).
How is PCR used in conjunction with gel electrophoresis to analyze DNA samples?
Polymerase chain reaction (PCR) is used to amplify specific regions of DNA in a sample. Gel electrophoresis is then used to separate the amplified DNA fragments based on size. By comparing the resulting DNA bands on the gel, scientists can analyze and identify the DNA samples.
How can the DNA sequencing technique shown in the virtual lab be used to identify other classes of pathogen's such as viruses?
The DNA sequencing technique can be used to identify viruses by isolating and extracting the viral DNA from a sample, sequencing it, and then comparing it to a database of known viral genomes. By matching the sequence obtained from the sample to known viral sequences, researchers can identify the specific virus present in the sample. This method is particularly useful for identifying novel or unknown viruses.
