amitosisthis is direct cell division in which the genetic material is not duplicated and hence its distribution to the
cancer cell division like all other biological processes is under genetic control certain genes must regulate the
significance of mitosis1 reproduction william bateson 1906 wrote whenever i observe a dividing cell under
cytokinesisit is defined as the division or cleavage of cytoplasmic part of the cells into two daughter cells it
telophasethis is the final stage of mitosis in which the mitotic spindle disappears and each polar chromosomal group is
anaphasethis phase is of shortest duration it begins with a sudden separation of the two chromatids of each due
metaphasethis is a period of short duration the chromosomes are at the stage of their maximum condensation and hence
prophasethis is the first and longest phase of mitosis at its beginning all 10 nm segments of chromatids chromonemata of the
diploidy and haploidy in the chromosomal complement given species not all the chromosomes are different from each other in fact
chromosomes and their organizationduring division phase the duplicated chromatin fibres become extremely shortened
