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) The polymerase chain reaction (PCR) is a technique widely used in molecular biology for analyzing and testing DNA. The DNA polymerase used to amplify a piece of DNA by in vitro enzymatic replication contributed to the name for this technology. The PCR process sets in motion a chain reaction in which the DNA template is exponentially amplified (copied).
