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 mitotic spindle continues to develop as more microtubules assemble and stretch across the length of the former nuclear area. Chromosomes become more condensed and visually discrete. Each sister chromatid attaches to spindle microtubules at the centromere via a protein complex called the kinetochore.

WebDuring prophase, the mitotic spindle begins to form outside the nuclear envelope from microtubule organizing centers (MTOCs), which are sometimes called centrosomes or centrospheres (see Chapter 11 ). In the fungi, the centrosomes are known as spindle pole bodies ( Aist and Williams, 1972 ). Web21. a cell division stage where the sister chromatid begins to separate andmove towards the poles 22.
