The abstract of this article talks about RT-PCR. Well what exactly is RT-PCR? RT-PCR stands for Reverse Transcription-Polymerase Chain Reaction. It is a technique used in genetic studies that allows the detection and quantification of mRNA , particularly in samples with limited quantities of extracted RNA. It is a very sensitive method that shows whether or not a specific gene is being expressed in a given sample. RT-PCR is a very important test in the field of Genetically-Modified Organisms (GMO's) because it gives researchers a mechanism to test whether any specific gene is turned on (active) or turned off (inactive). This allows researchers to identify the benefits of genetically-modified organisms with respect to their "natural" counterparts and search for any significant differences in which genes are expressed in the two types of organisms.
