Polymerase chain reaction (PCR)

Genetic research has exploded in recent decades with emerging technologies, breakthroughs in sequencing and the advancing sophistication of PCR. This brief overview examines a few applications or areas of genetic research and how PCR is used in these types of research. As the field of genetic research has branched out, so too has PCR. Tailored variations of PCR have now been developed and employed to validate research, to be a primary tool for search or for up and downstream analysis. What is genotyping: Genotyping uses sequencing information to determine genetic differences or variants in individuals or in biological populations. This type of technique is used to investigate a predetermined and very specific region of the genome.

Polymerase Chain Reaction (PCR)- Principle, Procedure, Types, Applications and Animation

PCR combines the principles of complementary nucleic acid hybridization with those of nucleic acid replication that are applied repeatedly through numerous cycles. Two short DNA sequences designed to bind to the start forward primer and end reverse primer of the target sequence is used in PCR. Taq polymerase: A thermally stable DNA polymerase originally isolated from the thermophilic bacterium Thermus aquaticus , which resist inactivation during denaturation temperatures and allows primer extension at high temperature. PCR machine increases and decreases the temperature of the PCR mixture in automatic, programmed steps which generates copies of the target sequence exponentially. Once the first round is completed, the process is repeated by cycling back to the first reaction temperature and the next round of denaturation, annealing, and extension is started an automatic process in thermocycler. This 3 steps temperature cycle is repeated approximately 30 times which results in exponential amplification of the target gene sequence. Labeled probe that is specific for the target gene sequence is used to detect PCR amplified gene product also known as amplicon.

Principles and applications of polymerase chain reaction in medical diagnostic fields: a review

Recent developments in molecular methods have revolutionized the detection and characterization of microorganisms in a broad range of medical diagnostic fields, including virology, mycology, parasitology, microbiology and dentistry. PCR is an excellent technique for the rapid detection of pathogens, including those difficult to culture. Along with conventional PCR techniques, Real-Time PCR has emerged as a technological innovation and is playing an ever-increasing role in clinical diagnostics and research laboratories. Due to its capacity to generate both qualitative and quantitative results, Real-Time PCR is considered a fast and accurate platform. The aim of the present literature review is to explore the clinical usefulness and potential of both conventional PCR and Real-Time PCR assays in diverse medical fields, addressing its main uses and advances.

Polymerase Chain Reaction PCR is a powerful method for amplifying particular segments of DNA, distinct from cloning and propagation within the host cell. This procedure is carried out entirely biochemically, that is, in vitro. PCR was invented by Kary Mullis in He shared the Nobel Prize in chemistry with Michael Smith in
