Chromosome in anaphase

WebAnaphase A chromosome movement involves a combination of microtubule shortening and translocation of the microtubule lattice that result from flux of tubulin subunits ( Fig. 44.14 ). The contributions of the two mechanisms vary among different cell types. WebAnaphase (from Ancient Greek ἀνα- ( ana-) 'back, backward', and φάσις (phásis) 'appearance') is the stage of mitosis after the process of metaphase, when replicated chromosomes are split and the newly-copied chromosomes (daughter chromatids) are moved to opposite poles of the cell. Chromosomes also reach their overall maximum ...
