WebThe number of new copies of the DNA sequence of interest doubles with each three-step cycle. Thus, if the PCR process is repeated 40 or 50 times, even small samples of … WebThe number of cycles is usually carried out 25–35 times but may vary upon the amount of DNA input and the desired yield of PCR product. If the DNA input is fewer than 10 copies, up to 40 cycles may be required to produce a sufficient yield. More than 45 cycles is not recommended as nonspecific bands start to appear with higher numbers of cycles. graphic designer for shell
