For today’s lab we will be using a technique called cleaved amplified polymorphic sequence (CAPS) analysis to determine student genotypes for the PTC gene. The PTC gene encodes a taste receptor that is responsible for the ability to taste PTC. Two common alleles (what does this mean?) are found in most human populations. ... Our first step is to isolate a small amount of DNA and to amplify the region containing the PTC gene with a technique known as the Polymerase Chain Reaction (PCR).
Biotechnology Lab Program
The purpose of this lab is to collect a DNA sample from the cells that line the inside of your mouth and to use this sample to explore one of the most powerful techniques in molecular biology- the Polymerase Chain Reaction, PCR. Although PCR has many applications, it is commonly used to produce many copies of a selected gene segment or locus of DNA. In criminal forensics, for example, PCR is used to amplify DNA evidence from small samples that may have been left at a crime scene.
Experiment 3: Polymerase Chain Reaction (PCR)
PCR requires that the flanking sequences of the target DNA be known, so that single stranded synthetic oligonucleotide primers can be generated. Once these have annealed to the target DNA the polymerase can synthesize the rest of the chain. ... Usually in practical situations PCR mixtures contain other components such as reaction buffers, sterile water, EDTA (to chelate the magnesium ions) and other minor reagents.

Polymerase Chain Reaction
Polymerase Chain Reaction (PCR) is a technique by which you synthesize mass quantities of DNA in vitro. For this reaction, the critical ingredients in the recipe are the DNA you wish to replicate, well designed primers (to anneal and provide the free 3’ hydroxyl needed for DNA synthesis), Taq polymerase, and abundant nucleotide triphosphates (NTP’s).

What is PCR (polymerase chain reaction)?
Polymerase chain reaction (PCR) is also a simple technique that acts as a perfect complement to gene cloning. They led to procedures for studying the regulation of individual genes, which have allowed molecular biologists to understand how aberrations in gene activity can result in human diseases such as cancer. The techniques spawned modern biotechnology, which puts genes to work in production of proteins and other compounds needed in medicine and industrial processes.
Polymerase Chain Reaction (PCR)
The polymerase chain reaction (PCR) is an enzymatic process that allows for the detection of specific genes within an environmental DNA sample. PCR utilizes short, user defined DNA sequences called oligonucleotide primers, the sequence of which are complementary to target regions of genes known to encode for specific microbial functions (e.g. contaminant degradation).
Polymerase Chain Reaction (PCR) Protocol
The DNA polymerase needs to be stable at high temperatures because we will repeatedly heat our reaction mix to separate the two strands of the DNA molecules. Taq DNA polymerase is similar to all other DNA polymerases in that it requires a preexisting piece of DNA as a starting point for synthesis. The requirement of a starting point by the DNA polymerase actually makes the PCR protocol a powerful technique.

Polymerase Chain Reaction (PCR): Introduction: The molecular technique called PCR is in vitro amplification of a specific segment of DNA using a thermostable enzyme. Although it is a fairly new technique, invented in 1985 by Cary Mullis, it is widely used in hundreds of labs all over the world. The PCR process makes millions of copies of DNA in just a few hours. It is a replication reaction, which uses reagents very similar to what is needed for DNA replication inside a cell.

The polymerase chain reaction (PCR) was developed in 1985 by Kary Mullis (Saiki et al., 1985; Saiki et al., 1988). It is a very powerful technique that has many uses in modern recombinant DNA technology. PCR allows the rapid amplification of very small amounts of sequence specific DNA (e.g., the two copies of a gene in a single somatic cell, or the single copy in a sperm or egg) (Li et al., 1988) to large amounts that can be easily analyzed (i.e. hundreds of millions of copies).

In 1983, Kary Mullis developed a new method of genetic amplification—the polymerase chain reaction [PCR] (Bartlett & Stirling, 2003). A little over 20 years later, PCR now is a common and often crucial technique used in medical and biological research laboratories for a variety of applications. ... Speedy detection allows public health officials to post warnings or close beaches on the same day that samples are collected, rather than keep contaminated beaches open while waiting on overnight lab results.

Detecting avian malaria: an improved polymerase chain
ABSTRACT: We describe a polymerase chain reaction (PCR) assay that detects avian malarial infection across divergent host species and parasite lineages representing both Plasmodium spp. and Haemoproteus spp. ... Although serology may be more sensitive than PCR (Jarvi et al., 2002), serological methods recognize antibodies to ma-laria rather than detecting the parasites themselves. Therefore, using this technique to interpret positive results as current in-fections depends on the assumption that birds carry the disease throughout their lifetime.
Real-Time PCR Analysis
Real-time quantitative PCR (qPCR) is a powerful technique for quantifying changes in gene expression by producing millions of copies of specific, targeted regions of complementary DNA (cDNA) that has been reverse transcribed from messenger RNA (mRNA). ...

In this lab you will prepare those two samples and a positive control (GMO-positive template DNA) for the polymerase chain reaction (PCR). ... Because PCR identifies a specific sequence of DNA and makes millions of copies of (or amplifies) that sequence, it is one of the most useful tools of molecular biology. Scientists use PCR to obtain the large amounts of a specific sequence of DNA that are necessary for such techniques as gene cloning, where DNA is physically moved from one genome to another.
