PCR is closely patterned after the natural DNA replication process (Saiki et al., 1985). Diagnosis of disease now a days is mostly laboratory dependent. ... Related Journals of PCR . Polymerase chain reaction (PCR) is essentially a selective DNA amplification technique commonlyapplied for genetic testing and molecular diagnosis because of its high specificity and sensitivity.PCR technologies as the key of molecular biology, has realized that the qualitative detection of absolute quantitative has been changed.

Rajalakshmi Pharmaceutical Analysis Department, Santhiram college of Pharmacy, Nandyal, Kurnool, Andhra Pradesh, India. 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 based on using the ability of DNA polymerase to synthesize new strand of DNA complementary to the offered template strand. 1.3 Real-time quantitative PCR – a definition 3 1.4 Practical and theoretical principles underlying real-time PCR 3 1.5 Real-time PCR instrumentation – an overview 12 1.6 Detection chemistries used in real-time PCR 16 1.7 Performing a real-time RT-PCR experiment 25 1.8 What lies ahead 29 References 30 Protocol 1.1 32 Protocol 1.2 33 polymerase chain reaction (PCR): It is a molecular technology aim to amplify a single or few copies of the DNA to thousands or millions of copies.
