Consider the double-stranded DNA molecule below. The gray segments in the middle represent the regions we’d like to amplify by PCR. Four different pairs of PCR primers (in blue) are shown below. Each primer is shown in the location it would anneal to its template strand. Which primer pair would best amplify the target region?
