Understanding Chromosome Condensation and Cohesion in Mitosis Biology Diagrams Mitosis is undoubtedly an extremely complex operation that needs to be conducted and controlled precisely under the penalty of dismantling genome integrity. One of the key steps in mitosis is chromosome condensation - the compaction of the chromatin into well-defined rod-shaped structures (for other recent reviews, see 1- 3). This process
Although chromatin condensation in mitosis is, at least in animal and plant cells, already apparent by light microscopy, assessments of the degree of compaction of mitotic chromatin in relation to its interphase state differ considerably, from two to fiftyfold as estimated by volume occupancy of an EGFP-H2B signal or by distance measurements of chromosome loci, respectively [1, 2].

Chromosome condensation, the formation of thread-like chromosomes from interphase chromatin, is one of the most striking and earliest-described morphological changes in cells entering mitosis. As a consequence of condensation, chromatids become compacted into threads, are imparted longitudinal rigidity to withstand spindle forces, and
ofthe SMC proteins fail to condense and segregate chromosomes in mitosis but remain able to perform spindle elongation cell division [30].

The chromosome condensation by polyamines and crowders is physiologically relevant, because cytosol is a crowded environment and polyamines are present in various cell types over a wide
