A critical review on PCR, its types and applications. Jagtar Singh 1, Niti Birbian 2, Shweta Sinha 2 and Akshra Goswami 2. 1 Associate Professor, Department of Biotechnology, Panjab University Estimated Reading Time: 4 mins. Polymerase Chain Reaction, 12/ 5 MgCl 2 The concentration of MgCl 2 influences the stringency of the interaction between the primers and the template DNA. The range of MgCl 2 usually tested is from - 4 mM in mM increments, while the default starting point is often is mM. 1. RT-PCR refers to PCR that uses product of an Reverse Transcription (RT) reaction as template 2. A variant of polymerase chain reaction (PCR) 3. A technique commonly used in molecular biology to detect RNA expression 4. RT-PCR is often confused with real-time polymerase chain reaction (qPCR) 5. RT-PCR is used to qualitatively detect gene.

PCR amplification can turn a few molecules of a specific target nucleic acid (too little to be analyzed directly or used in biochemical reactions) into as much as a microgram of DNA. PCR is closely patterned after the natural DNA replication process (Saiki et al., ). Two oligonucleotide primers flank and define the target sequence to be. Nested PCR. Nested PCR is the improvement of the polymerase chain reaction that enhances its specificity. It reduces the nonspecific binding of products. The nested PCR technique uses two sets of primers. The first one takes part in the 1st PCR reaction. Then, the second is utilized in the product of the first reaction for amplifying purposes.
The Polymerase chain reaction (PCR), first envisaged in by Kary Mullis, has revolutionized life sciences and has become an essential technique in many aspects of science, including clinical diagnostics, forensics and genetic engineering. Polymerase Chain Reaction: Types, Utilities and Limitation s Multiplex PCR Multiplex PCR is an adaptation of PCR which allows simultaneous amplification of many sequences. This technique is used for diagnosis of different diseases in the same sample [8, 9]. Multiplex PCR can detect different pathogens in a single sample [10, 11, 12]. Polymerase Chain Reaction, 12/ 7 melting temperature of primer-template DNA duplex. In most cases the T A is between 50 and 65o C. However, if nonspecific PCR products are obtained in addition to the expected product, the annealing temperature should be optimized by increasing it stepwise by o C. Extension.
