for sequencing.
You must however start with a PCR product, and use quite a bit of it 
(1-10%), this ensures that the Taq doesn't extend your primer
indefinately, e.g if you used genomic DNA.
The amplification will not be exponential, but linear for obvious
reasons, hence the requirement for sufficient template.
