Including chromosome assembly and segregation
WebThe aim of the mitotic process is to segregate the genetic material packed into duplicated chromosomes equally between two daughter cells. To accomplish this, cells form a highly dynamic yet robust structure called the mitotic spindle [1,2,3].In the majority of higher eukaryotes, chromosomes attach to spindle microtubules (MTs) by kinetochores, large … WebThe fundamental role in chromosome condensation is carried out by two multiprotein complexes: condensin I and condensin II. Both complexes contain the same pair of …
