Polymerase chain reaction (PCR) amplifies DNA following the equation.
A
$N^{2}$
B
$2^{n}$
C
$2n+1$
D
$2N^{2}$
Explanation
DNA amplifies exponentially as $2^n$ in PCR.
Detailed Solution
In PCR, each cycle doubles the amount of target DNA. Thus, after $n$ cycles, DNA molecules increase by a factor of $2^{n}$.
