Chromosome with kinetochore

WebPulling forces generated by kinetochore microtubule attachments pull sister chromatids apart in anaphase once cohesin is cleaved (on satisfaction of the spindle assembly checkpoint). WebA kinetochore, a large, multimeric protein, joins the two strands at this section. You may remember hearing about the kinetochore while studying mitosis - it helps guide the DNA along the spindle fibres. My guess is that the kinetochore bonds to the DNA via ionic or polar bonds (i.e., it contains some sort of DNA binding domain).

Microtubules grow from centrosomes placed at opposite poles of the cell. The microtubules move toward the middle of the cell and attach to one of the two fused homologous chromosomes.
