The table shows the spectral analyses for the averaged auto-correlations of pSymA (pSymA) and of pSymA with the genes' positions randomly permutated (rnd pSymA) for data set A and set B. Shown are the first twenty periods with the highest amplitudes, in descending order and the number of periods contained on the replicon. The two spectra of the "real" plasmid are made up of short and long periods. Both have, for example, periods of 108 and 206 genes. The random permutations, however, have only very short periods. The amplitudes for pSymA in set B are lower compared to the set A, as we are looking at a random phenomenon, which is necessarily weaker than active transcription. "No of periods": how many periods can be fitted along the replicon in question.
