Image Taq polimerase.png thumb Structure of TaqpolymeraseTaq DNA polymerase A polymerase EC 2.7.7.6 7 19 48 49 is an enzyme whose central function is associated with polymer s of nucleic acid s such as RNA and DNA . The primary function of a polymerase is the polymerization of new DNA or RNA against an existing DNA or RNA template in the processes of DNA replication replication and Transcription genetics transcription . In association with a cluster of other enzymes and proteins, they take nucleotide s from solvent, and catalyse the synthesis of a polynucleotide sequence against a nucleotide template strand using base pairing interactions. It is an accident of history that the enzymes responsible for the catalytic production of other biopolymer s are not also referred to as polymerases.

Polymerase stuttering is the process by which a polymerase Transcription genetics transcribe s a nucleotide several times without progressing further on the mRNA chain. It is often used in addition of poly A tail s or 5 cap capping mRNA chains by less complex organism s such as viruses. Process A polymerase may undergo stuttering as a probability controlled event, hence it is not explicitly controlled by any mechanisms in the translation process. Generally, it is a result of many short repeated ribosomal frameshift frameshift s on a slippery sequence of nucleotide s on the mRNA strand ref Anderson EC, Hunt SL, Jackson RJ.

For the measure of viral plaques Plaque forming unit DISPLAYTITLE Pfu DNA polymerase Pfu DNA polymerase is an enzyme found in the hyperthermophilic archaeon Pyrococcus furiosus , where it functions in vivo to replicate the organism s DNA . In vitro , Pfu is used to amplify DNA in polymerase chain reaction PCR processes, where the enzyme serves the central function of copying a new strand of DNA during each extension step. Proofreading ability of Pfu polymerase The main difference between Pfu and alternative enzymes is Pfu s superior thermostability and proofreading properties compared to Taq DNA polymeraseTaq DNA polymerase . Unlike Taq DNA polymerase, Pfu DNA polymerase possesses 3 to 5 exonuclease proofreading activity, meaning that it works its way along the DNA from the 5 end to the 3 end and corrects nucleotide misincorporation errors. This means that Pfu DNA polymerase generated PCR fragments will have fewer errors than Taq generated PCR inserts. As a result, Pfu is more commonly used for molecular cloning of PCR fragments than the historically popular Taq . Citation needed date May 2012 Commercially available Pfu typically results in an error rate of 1 in 1.3 million base pairs and can yield 2.6 mutated products when amplifying 1 kb fragments using PCR. However, Pfu is slower and typically requires 1&ndash 2 minutes per cycle to amplify 1kb of DNA at 72 C. Using Pfu DNA polymerase in PCR reactions also results in blunt ended PCR products. Pfu DNA polymerase is hence superior to Taq DNA polymerase for techniques that require high fidelity DNA synthesis, but can also be used in conjunction with Taqpolymerase to obtain the fidelity of Pfu with the speed of Taqpolymerase activity.

Image Nested PCR.png thumb 250px A diagram illustrating the method of nested PCR. Nested polymerase chain reaction is a modification of polymerase chain reaction intended to reduce the contamination in products due to the amplification of unexpected primer binding sites. Polymerase chain reaction itself is the process used to amplify DNA samples, via a temperature mediated DNA polymerase . The products can be used for sequencing or analysis, and this process is a key part of many genetics research laboratories, along with uses in DNA fingerprinting for forensics and other human genetic cases. Conventional PCR requires primer molecular biology primers complementary to the termini of the target DNA. A commonly occurring problem is primers binding to incorrect regions of the DNA, giving unexpected products. Nested polymerase chain reaction involves two sets of primers, used in two successive runs of polymerase chain reaction, the second set intended to amplify a secondary target within the first run product. Processes The target DNA undergoes the first run of polymerase chain reaction with the first set of primers, shown in green. The selection of alternative and similar primer binding sites gives a selection of products, only one containing the intended sequence. The product from the first reaction undergoes a second run with the second set of primers, shown in red. It is very unlikely that any of the unwanted PCR products contain binding sites for both the new primers, ensuring the product from the second PCR has little contamination from unwanted products of primer dimers, hairpins ...
