The principle behind Sanger sequence technique are as follows:
1.A DNA primer must be attached to the template strand by hybridisation. Deoxynucleosides triphosphates must be sequentially added to the primer strand.
2.The primer must be designed for the known sequences at the end of the template strand.
3.M13 sequences should be generally attached and the primer of M13 is made.
4.The reaction mixture containing dideoxynucleoside triphosphate along with usual dNTPs.
5.During replication if ddNTPs is included instead of usual dNTPs, the growing DNA strand then the replication stops at that nucleotide
6.The ddNTP is analogue of dNTP
7.ddNTP of dNTP ends chain at its respective site.

In this technique, firstly you have to prepare template. Next generate nested set of fragments. This is followed by electrolysis and gel reading.
