slava [35]

A five-cycle PCR process is started with a single DNA duplex. How many copies of your sequence, in theory, do you have right now? 32.

<h3>What is the PCR?</h3>

1) PCR, or polymerase chain reaction, is a method for producing several copies of a particular DNA region in vitro (in a test tube rather than an organism).

2) Taq polymerase, a thermostable DNA polymerase, is used in PCR, and DNA primers made especially for the desired DNA region are necessary.

3) PCR allows for the production of several copies of the target region by cycling the reaction repeatedly through a series of temperature changes.

4) PCR has a wide range of useful research applications. It is frequently employed in forensic analysis, medical diagnostics, and DNA cloning.
