After 12 pcr cycles how many dna strands would be available?

PCR or polymerase chain reaction refers to a procedure used to exponentially increase a particular target DNA sequence, permitting the sequencing, isolation, or cloning of a single sequence in many.  

The number of double-stranded DNA segments is doubled in each of the cycles so that after n cycle one will have 2^n copies of DNA. For example, after 10 cycles one will have 1024 copies of DNA strands. Therefore, after 12 cycles of PCR one will have about 4096 copies of DNA strands.
