you are performing a PCR of one 1,000 base pair long fragment of DNA. Before the first cycle you have 10 copies of this fragment.

you are performing a PCR of one 1,000 base pair long fragment of DNA. Before the first cycle you have 10 copies of this fragment. how many cycles of PCR will you need to have 10 ng of DNA of this fragment?( the average weight of one base pair is 600 da( 1 da=1 g/mole there are about 6.10^23 entities
