Operation | Five basic "ingredients" are needed to prepare a polymerase chain reaction. • DNA template to be transcribed • Raw materials, short stretches of DNA that initiate polymerase chain reaction (PCR), designed to adhere to either side of the DNA segment you want to transcribe • DNA nucleotide bases (also known as dNTPs). DNA bases (A, C, G, and T) are the building blocks of DNA and are necessary to build a new strand of DNA • Taq polymerase enzyme to add new DNA bases • Buffer to ensure proper conditions for the reaction. The polymerase chain reaction process involves a heating and cooling process called the thermal cycle which is carried out by a machine. There are three main stages: 1. Denaturing - when a double-stranded DNA template is heated to separate it into two single strands. 2. Annealing - when the temperature is reduced to enable the DNA primers to stick to the DNA template. 3. Expansion - When the temperature rises and the new strand of DNA are formed by the enzyme Taq polymerase. These three phases are repeated 20-40 times, doubling the number of DNA copies each time. |
