In order to check the robustness of our chromosome partitioning method, the same analysis was performed on two biological replicates of the Hi-C data set , and the consistency between partitioning schemes across data sets was tested using mutual information. Briefly, to be consistent, … The parABS system is a broadly conserved molecular mechanism for plasmid partitioning and chromosome segregation in bacteria. Originally identified as a genetic element required for faithful partitioning of low-copy-number plasmids, it consists of three components: the ParA ATPase, the ParB DNA-binding protein, and the cis-acting parS sequence.
