sentences:  By rotating, the minicircles of the daughter kinetoplast are assembled in a spiral fashion and begin moving inward toward the center of the disk as new minicircles are unlinked and moved into the KFZ for replication.While the exact mechanisms for maxicircle kDNA have yet to be determined in the same detail as minicircle kDNA, a structure called a "nabelschnur" (German for "umbilical cord") is observed that tethers the daughter kDNA networks but eventually breaks during separation.Using FISH probes to target the nabelschnur, it has been found to contain maxicircle kDNA.
