We chose to divide the code into two separate parts for two reasons. Firstly, being split into two equally long parts at each end of the coding sequence ensures symmetry, which again should help make insertion of a watermark easy, as this will reduce the complexity of the primers we need to design to insert them. Secondly this ensures that identification is done easily, since the combination of nucleotides of the sequence from E to X and from S to P is known. Thus we effectively increase the sequence we search for from 6 to 26 nucleotides.  Also this means that the risk of a naturally occurring combination of nucleotides, identical to the synthetically created one decreases.

Sequencing the part should therefore yield the watermark, which could then be accessed, read and understood.
