About I billion copies of a DNA region will be produced after 30 cycles in the PCR machine.
How many numbers of DNA are there after 30 cycles of PCR?
In 30 cycles, even if the cycle started with only a single strand of DNA, when it has been amplified, it is said to become more than a billion copies ( that is about 230 = 1.02 x 109).
Conclusively, note that in every new DNA piece about 1 million copies of a single fragment of DNA can be gotten from it.
