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) is a molecular biological technique for amplifying (creating multiple copies of) DNA without using a living organ ism, such as E. coli or yeast.olymerase Chain Reaction (PCR). Polymerase chain reaction (PCR) is a laboratory technique used to amplify DNA sequence s. The method involves using short DNA sequence s called primer s to select the portion of the genome to be amplified. PCR (polymerase chain reaction).
