Vectorette PCR is similar to PCR with the difference being that it is capable of obtaining the sequence desired for amplification from an already known primer site. While PCR needs information of already known sequences at both ends, Vectorette PCR only requires previous knowledge of one. This means that is able to apply the method of PCR which needs sequence information from both ends to fragments of DNA that contain the information of the sequence at only one end and not the other. In order to achieve this, there are specific steps that this method must first go through. These steps have been researched for the purpose of discovering the scientific uses of Vectorette PCR and how they can be applied.
