Specific Protocols

BioBricks:Sequencing DNA -- protocol for DNA sequencing of BioBrick parts

Notes

At least at the biopolymers facility and probably true for most sequencing results, when doing a run-off sequencing reaction, an extra (sometimes pretty high amplitude) 'A' peak is seen at the end before the template ends. The workers at the biopolymers facility seemed surprised when they were told about this, but they were able to find out that the sequenase enzyme used in the sequencing reaction is a genetically modified form of Taq. Therefore, it is most probable that the extra A is the template-independent A that Taq tends to add to the 3'-end of DNA.
