What discovered tag polymerase?
Tag polymerase, also known as Taq polymerase, was discovered in 1976 by researchers at Cetus Corporation. Taq polymerase is a heat-resistant enzyme that is commonly used in polymerase chain reaction (PCR) due to its ability to withstand high temperatures required for DNA amplification. This discovery revolutionized molecular biology research by enabling the automation and rapid amplification of DNA sequences.
Is DNA polymerase used in the process of transcription?
No, DNA polymerase is not used in the process of transcription. Transcription is the process of making an RNA copy of a gene from DNA, and it is carried out by an enzyme called RNA polymerase. DNA polymerase is primarily involved in the process of DNA replication.
Process used to amplify small DNA samples?
Polymerase chain reaction (PCR) is a commonly used method to amplify small DNA samples. In PCR, the DNA sample is heated to separate the double-stranded DNA into single strands, then specific primers are added to flank the target DNA sequence. DNA polymerase then synthesizes new DNA strands complementary to the target sequence, resulting in exponential amplification of the DNA fragment.
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 of the following reactions is used to radioactively label DNA?
The reaction that is commonly used to radioactively label DNA is the nick translation method, where a DNA molecule is treated with a DNA polymerase, dNTPs (including radioactive ones), and a DNAase to create radioactive labeled DNA fragments.
What is the source of the polymerase used in polymerase chain reaction?
The polymerase used in polymerase chain reaction (PCR) is typically derived from a thermophilic bacterium called Thermus aquaticus. The specific polymerase most commonly used is Taq polymerase, which is known for its ability to withstand high temperatures required for PCR.
Is vent polymerase a thermostable enzyme?
Yes, Vent polymerase is a thermostable enzyme. It is derived from the Thermococcus species and is able to withstand high temperatures, making it suitable for use in applications that require high-temperature conditions such as polymerase chain reaction (PCR).

What does the medical abbreviation PCR mean?
PCR stands for "polymerase chain reaction," which is a molecular biology technique used to amplify and detect specific DNA sequences. It is commonly used in medical diagnostics and research to detect viruses, bacteria, and genetic mutations.
Is the enzyme that allows replication to occur DNA polymerase or RNA polymerase?
DNA polymerase replicated DNA. RNA polymerase creates mRNA to be used in protein synthesis. RNA polymerase does not replicated DNA.
Is DNA polymerase used in the process of transcription?

What is the significance of thermostable polymerase in DNA technology?
Thermostable polymerase, like Taq polymerase, is important in DNA technology because it can withstand the high temperatures used in polymerase chain reaction (PCR). This allows for the rapid amplification of DNA fragments without the need to constantly replenish the enzyme. This polymerase is derived from thermophilic bacteria and is essential for the success of PCR in molecular biology applications.
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 of the following reactions is used to radioactively label DNA?
The reaction that is commonly used to radioactively label DNA is the nick translation method, where a DNA molecule is treated with a DNA polymerase, dNTPs (including radioactive ones), and a DNAase to create radioactive labeled DNA fragments.
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
