To get around this problem, you decide to use a specialized application of DNA replication, called the polymerase chain reaction (PCR). In PCR, DNA is isolated from skin cells, a blood smear, or even a few hairs and subjected to repeated rounds of replication. Not all the DNA is copied, only those unique target sequences that can be used for identification are replicated. With each round, the number of copies of target DNA doubles. For these questions, assume that there was only 1 copy of target in the initial sample of DNA. How many copies would there be after one round of PCR
