In one study, the interactive evolutionary algorithm was used to design book covers [18], and the k-means clustering method was used to reduce user fatigue so that only the centroid of each cluster was shown to the user.
Recently the dnd cluster was shown to mediate the incorporation of sulphur into the DNA backbone via a sequence-selective, stereo-specific phosphorothioate modification in Escherichia coli B7A.
This cluster was shown previously to be a strong TSE silencer whereas all the clusters without any rearrangement cannot induce TSE [51].
More recently the dnd cluster was shown to mediate the incorporation of sulphur into the DNA backbone via a sequence-selective, stereo-specific phosphorothioate modification in E. coli B7A [3].
The pel (pellicle) gene cluster was shown to be involved in the formation of a pellicle, a surface-associated biofilm on the air-liquid (A L) interface in standing cultures [13], [14].
The toxin microcystin synthetase (mcy) gene cluster was shown to be of ancient origin [ 52].
