Amplification of a DNA fragment by PCR yields only one faint band of the expected size on an agarose gel. For such a sample, the best way to increase the yield of the PCR product is to
1
Decrease magnesium ion concentration.
2
Decrease annealing temperature.
3
Use shorter primers.
4
Increase extension time
