Spinach is the quintessential healthy food, and itâs no surprise that itâs also high in potassium. Bananas get a lot of attention for their potassium content, but ounce for ounce spinach bests them in the potassium department.
New Applications. Quantitative polymerase chain reaction (qPCR) is used to simultaneously detect a specific DNA sequence in a sample and determine the actual copy number of this sequence relative to a standard. In real-time PCR, the DNA copy number can be established after each cycle of amplification.
Polymerase Chain Reaction (PCR). PCR is a laboratory method used for making a very large number of copies of short sections of DNA from a very small sample of genetic material. This process is called amplifying the DNA and it enables specific genes of interest to be detected or measured.his method is used to measure the amount of DNA that is present in a sample. RT â PCR (Reverse Transcriptase PCR). This method uses PCR to amplify RNA. RNA is a single stranded nucleic acid molecule and needs to be made into DNA before it can be amplified.
