Question

how many molecules of DNA would result from one molecule after three cycles of PCR

Answer 1

$\huge\underline\mathfrak\blue{Solution}$

PCR, assuming sufficient primers, dNTP's, and polymerase molecules, doubles the number of target DNA molecules

Answer 2

Answer:

16 copies of molecules of DNA would result from one molecule after three cycles of PCR.

Explanation:

PCR can be expanded as Polymerase Chain Reaction. It is one of the techniques followed in labs, where massive copies of DNA fragments could be made. There are three stages to be followed while doing PCR. They are 1) denaturing, 2) annealing, and 3) extending. Each of these stages can get repeated at least 20 to 30 times to get more copies. The first cycle will have $2^{2} \text { copies }$, second cycle would be $2^{3} \text { copies }$, third cycle would be $2^{4}$, which 16 copies.
