Hi,I am doing 3'RACE  PCR in the purpose to amplify  the  new sequence from the 3' end. I have successfuly amplified a band
which looks like the  PCR product. After that I used several gene specific primers combing with the universal primer for further 
PCR in order to know what the PCR product is. The PCR were worked and I got single band from each PCR reactions with 
respected size. Sequence reaction proved that this PCR product was a combination of known sequence and the unknown one.
My question is how can trust this result? Whether it is possible that DNA amplification can jump from one template to another duing 
the process of the PCR because for some unknown reason, PCR sometimes gives us the weild result.Thank you for your help.
