Mitosis and de-condensed all through interphase

Question

Why is it significant for chromosomes to be condensed throughout mitosis and de-condensed all through interphase?

Answer 1

Throughout mitosis the main difficulty to be resolved is the accurate separation of chromosome sets between daughter cells. When chromosomes were de-condensed long tiny fibers of DNA would be scattered in cytoplasm after the karyotheca breaking and chromosomes could not be simply organized and pulled by spindle fibers.

Throughout interphase the function of chromosomes, that is, of DNA molecules, is the synthesis of RNA and therefore of proteins. For this task it is essential for functional molecular areas to be de-condensed (such areas form the euchromatin). Throughout interphase in addition to DNA replication takes place as a preparatory step for cell division. In this procedure it is fundamental for the exhibition of DNA molecules to serve as templates to latest DNA chains under production.
